Ceramic Antenna vs PCB Antenna
PCB antenna is most used in the market, both types have their own strengths and limitations. When selecting an antenna for your application, which is the best? Herein, Best Technology will breakdown their differences in detail:
1. Material and Construction
A ceramic antenna is made from high-quality dielectric ceramic material, it is usually a standalone component that can be soldered onto a PCB. In contrast, a PCB antenna is simply a copper trace printed on the PCB itself, using the boardâs material as the dielectric. PCB antennas require precise layout design to function effectively and are directly integrated into the boardâs circuitry.
2. Size and Space Efficiency
Ceramic antennas are compact and self-contained, since they do not rely on a large ground plane, they can be placed in confined areas without significant loss in performance. PCB antennas, however, require a larger surface area to achieve good performance, as their efficiency is heavily dependent on ground plane size. In very small devices, a PCB antenna may not be practical due to space constraints.
3. Manufacturing and Design Flexibility
A PCB antenna is cost-effective and easy to manufacture since it is created directly on the PCB during the etching process. This eliminates the need for additional components, reducing bill of materials (BOM) costs. However, PCB antennas require careful tuning and optimization, so its design and manufacturing process more complex.
4. Cost and Production Considerations
PCB antennas are generally cheaper to produce, as they are just part of the PCB layout and do not require separate assembly. However, the hidden cost comes in the form of design complexity, tuning, and potential performance issues. Ceramic antennas, while having a higher unit price, reduce design time and improve reliability, leading to lower costs in the long run for high-performance applications.
How Does a Ceramic Antenna Work?
âThe working principle of ceramic antenna PCB â mainly includes two processes of transmitting and receiving. The ceramic antenna uses GPS satellite to realize navigation and positioning. The main task of the user’s receiver is to extract the pseudo-random noise code and data code in the satellite signal, so as to solve the navigation information of the receiver carrier such as position, speed and time (PVT). Here is a detailed explanation for each process:
Signal Transmission â The antenna converts electrical signals into electromagnetic waves.
Signal Reception â It captures incoming RF signals and converts them back into electrical signals.
Impedance Matching â A matching network ensures efficient energy transfer between the antenna and the circuit.
Ground Plane Interaction â A well-designed ground plane improves signal stability and efficiency.
Ceramic Chip Antenna Design Considerations
Designing a ceramic chip antenna involves several factors that influence performance. Here are the key considerations:
1. Antenna Placement on the PCB
Antennas should be positioned at the edge or corner of the PCB to maximize radiation efficiency. Nearby metal components, shielding, or large ICs should be avoided as they can cause signal interference.
2. Ground Plane Size and Layout
A larger ground plane improves antenna efficiency by acting as a signal reflector. The PCB material should match the antennaâs specifications to maintain frequency accuracy.
There should be no copper traces, ground planes, or metal components too close to the antenna. Keeping the antenna away from batteries, shields, and enclosures.
5. Operating Frequency and Bandwidth Considerations
Each ceramic antenna is designed for a specific frequency, such as 2.4GHz for Wi-Fi/Bluetooth or 1.575GHz for GPS. Any change in PCB layout can shift the resonance frequency, requiring fine-tuning.

DC and AC inverters are essential components in todayâs energy systems. Whether youâre harnessing the power of the sun with solar panels, working with backup power solutions, or simply need a way to power your devices, understanding how these inverters work is crucial. This blog breaks down the purpose, advantages, and practical use of DC and AC inverters, helping you make informed decisions based on your needs.
What is a DC and AC Inverter?
Inverters are electrical devices that convert DC (direct current) to AC (alternating current), or vice versa. Typically, DC power comes from sources like batteries or solar panels, while AC is what you use to power most household appliances. A DC to AC inverter is used to convert the DC power into usable AC power. On the other hand, an AC to DC inverter does the reverse, converting AC power into DC to charge batteries or power DC devices.
In simple terms, a DC to AC inverter allows you to use power from sources like batteries or solar panels in everyday devices that require AC power, such as fans, lights, and even refrigerators. Without inverters, it would be challenging to use energy from renewable sources for traditional home appliances.
What is the Purpose of a DC to AC Inverter?
The primary purpose of a DC to AC inverter is to make DC power usable for AC appliances. Whether you’re working with a solar power system or simply need backup power, inverters are the key to making this energy conversion happen. For example, if youâre using a solar panel setup, you typically generate DC power. Since most home appliances run on AC, you need an inverter to convert that energy into a form you can use.
Inverters are essential in off-grid applications, such as in remote areas, where the electricity grid is unavailable. They provide an efficient way to use stored DC power, converting it into AC electricity for devices that would otherwise be useless.
How Does an Inverter Work When There is No Electricity?
When there’s no grid electricity, inverters can still work by drawing power from other sources like batteries or solar panels. This is particularly helpful in off-grid or emergency situations. The inverter takes the DC power from your stored energy and converts it into AC power to keep your appliances running.
For example, if you have a solar power system with a battery backup, and the power goes out, the inverter allows you to keep your appliances on, as long as your batteries have enough charge. In this way, inverters provide an essential role in maintaining power continuity during outages.
DC Inverter AC Advantages and Disadvantages
DC inverters come with several benefits, particularly in renewable energy applications like solar power systems. They are highly energy-efficient and help convert power from DC sources into usable AC power without much loss. This makes them perfect for off-grid living or areas where solar panels are the primary source of energy.
However, there are some drawbacks. DC inverters may have higher upfront costs, and the complexity of conversion can lead to minor energy losses. They also tend to require more maintenance due to the way they manage energy conversion.
On the flip side, AC inverters are generally more efficient in household and industrial settings because AC power is more compatible with most appliances. Their downside lies in the additional energy needed to convert AC power into usable DC energy when dealing with solar systems or battery charging applications.
Despite these differences, both types of inverters have their place, and their advantages often outweigh the disadvantages when used in the right scenarios.
Which is Better: AC Inverter or DC Inverter?
Choosing between an AC and DC inverter depends on your specific needs. AC inverters are more commonly used for residential and industrial applications, as they are designed to power traditional household appliances. They are easy to integrate into existing power systems and typically provide a reliable power source for most needs.
On the other hand, DC inverters are especially useful for renewable energy applications. If you’re installing solar panels or using a battery backup, a DC inverter is the best choice, as it can convert the stored DC power into AC power for your home. They are also more energy-efficient in off-grid situations, where you rely entirely on solar or battery power.
Ultimately, the “better” inverter is the one that fits your particular power needs. If you’re on the grid or need to power AC devices from a DC source, an AC inverter is the way to go. But for renewable energy setups, DC inverters are a better fit.
How Long Will a 12V Battery Last with an Inverter?
The lifespan of a 12V battery when used with an inverter largely depends on the wattage of the devices you’re powering. Inverters typically drain the battery at different rates based on the energy demand of the connected devices. For instance, if youâre running a light or small appliance, the battery can last for several hours. However, larger appliances like refrigerators or air conditioners will drain the battery much faster.
On average, a 12V battery can provide power for anywhere from 3 to 10 hours with an inverter, depending on the load. It’s essential to size your inverter and battery capacity properly to ensure your system works efficiently. By balancing energy use with battery life, you can maximize the performance of your inverter system.
How to Choose a DC AC Inverter?
Choosing the right DC to AC inverter involves considering several factors. First, determine the type of devices youâll be powering. Consider the total wattage your devices require. Inverters come in various sizes and capacities, so itâs essential to match the inverterâs output with your needs.
Next, consider the efficiency of the inverter. More efficient models will waste less power and give you better performance, especially if you’re using renewable energy sources like solar power. You should also think about the inverter’s durability, features like surge protection, and whether it has any warranties or support.
The inverterâs voltage rating must also align with your power system. For example, in a 12V system, you should choose a 12V DC to AC inverter. Also, remember to check the inverterâs surge capacity, especially if youâre powering devices with a high initial startup load, like motors.
Why PCB is Important in DC and AC Inverters?
PCBs (Printed Circuit Boards) play a crucial role in both DC and AC inverters by providing the necessary connections and support for various electrical components. Inverters rely on PCBs to ensure proper functionality, reliability, and safety. For DC to AC conversion, the PCB helps in routing the signals between critical components like transistors, diodes, and capacitors, ensuring the conversion process runs smoothly.
In both types of inverters, the PCB also helps dissipate heat, manage power efficiently, and prevent potential short circuits. High-quality PCBs are essential for maintaining the long-term durability and performance of inverters, particularly in energy-intensive applications like solar or backup power systems. The design, material quality, and structure of the PCB can directly affect the efficiency and lifespan of the inverter, making it a key component in any inverter system.

FAQs of PCB Assembly
1. What is the difference between PCB and PCB assembly?
A PCB (Printed Circuit Board) is the bare board with copper traces, while a PCB Assembly (PCBA) includes all the necessary electronic components soldered onto the board, making it a fully functional unit ready for use.
2. What is the purpose of a pick and place drawing in the SMT process?
A pick and place drawing provides detailed guidance for automated SMT machines, specifying component placement, orientation, and reference designators on the PCB. It ensures accurate positioning (including polarity indicators for diodes and capacitors) and facilitates post-assembly inspection.
3. What are counterbores and countersinks?
Counterbore: A cylindrical recess with a flat bottom, designed to allow a screw head to sit flush with the PCB surface. Commonly used with flat-head screws to ensure secure mounting, such as for attaching heatsinks or connectors.
Countersink: A conical recess that matches the angle of a tapered screw head, such as self-tapping screws. Helps create a smooth, low-profile surface, often used when securing PCBs within enclosures.
The key difference is that counterbore provides a level surface by embedding the screw head within the material. Countersink features a tapered design that aligns the screw and evenly distributes stress.
4. How to distinguish the PTH & NPTH?
PTH is PLATING Through Hole, it has copper in the holes inside, which can be conductive. NPTH is Non PLATING Through Hole, which donât have copper inside the holes. Through holes means through the top and bottom on the PCB, it could be PTH and NPTH.
As one of the most widely used antenna designs, a dipole PCB antenna plays a critical role in radio transmission, IoT devices, and RF applications. Whether it is used in Wi-Fi routers, mobile networks, or radar systems, the dipole antenna PCB ensures stable and reliable signal transmission.
What is a Dipole Antenna PCB?
A dipole antenna PCB is a printed circuit board-based antenna designed with two conductive elements that serve as radiating arms. The word “dipole” means “two poles,” which describes the two symmetrical elements that make up the antenna. The length of these elements is typically half the wavelength of the frequency it operates on, which is why it is often called a half-wave dipole antenna.
This type of antenna is widely used in RF applications due to its simple construction, ease of manufacturing, and effective radiation properties. A dipole antenna PCB is commonly found in wireless communication systems, radio transmitters, satellite communication, and IoT devices. The radiation pattern of a dipole antenna is omnidirectional, making it ideal for applications that require uniform signal coverage.
Dipole PCB Antenna Design
Same as others antenna PCBs, designing a dipole PCB antenna requires careful consideration of factors such as frequency, impedance, substrate material, and radiation efficiency. The key aspects of designing a dipole PCB antenna include:
1. Determining the Antenna Length
The total length of a half-wave dipole antenna is calculated using the formula:
Where:
L = Length of the dipole antenna
λ = Wavelength of the signal
c = Speed of light (3 Ă 10^8 m/s)
f = Operating frequency
For example, for a 2.4 GHz Wi-Fi application, the length of a half-wave dipole antenna would be approximately 62.5 mm.
2. Choosing the Substrate Material
The choice of PCB substrate material affects the antennaâs efficiency and performance. The most common substrates used in dipole antenna PCB design include:
FR-4: Low-cost but has higher dielectric loss, suitable for general applications.
Rogers RO4000 Series: Low-loss, high-performance material for RF applications.
PTFE (Teflon): Ideal for high-frequency applications due to its low dielectric constant.
3. Impedance Matching
A standard dipole antenna has an impedance of 73 ohms in free space. To maximize power transfer, the impedance of the antenna must be matched with the feedline and transmitter, typically using a 50-ohm transmission line. This can be achieved through matching networks or baluns (balanced-to-unbalanced transformers).
4. Feed Mechanism
A dipole PCB antenna can be fed using:
Coaxial Feed: A direct connection to a 50-ohm coaxial cable.
Microstrip Feed: Uses a microstrip transmission line on the PCB for integration with circuits.
Balun Feed: Improves performance by converting an unbalanced signal into a balanced one.
Working Principle of Dipole Antenna PCB
A dipole antenna PCB operates based on the principle of electromagnetic radiation. It typically consists of two symmetrical conductive elements, arranged in a straight or semicircular configuration, which function as the transmitting and receiving elements. These two conductor arms are fed at the center, forming a half-wavelength antenna. The current distribution on the dipole antenna resembles that of an open transmission line, with current nodes appearing at both ends.
When an alternating current (AC) signal is applied at the feed point, the current oscillates along the dipole arms, generating an electric field. This interaction with the surrounding environment results in the propagation of electromagnetic waves. The efficiency of radiation depends on the length and shape of the conductors. Typically, a dipole antenna is designed with a length of 1/2 or 1/4 of the wavelength of the intended signal to maximize radiation performance. The working process shows as below:
In PCB design, placing a ground layer beneath the antenna can create a mirror effect, enhancing its performance. Additionally, careful PCB layout adjustments and ground layer configurations can optimize the antenna’s radiation efficiency and directivity, improving overall signal strength and stability.
Dipole Antenna PCB Advantages
Simple structure and easy to manufacture: The dipole antenna consists of two conductors of equal length, with a simple structure, easy to manufacture and maintain, and low cost.
Omnidirectional radiation: Dipole antenna can form a strong radiation field in two opposite directions, with omnidirectional radiation characteristics, suitable for applications that require uniform coverage of the surrounding environment, such as Wi-Fi hotspots or mobile base stations.
Good radiation pattern: The radiation pattern of the dipole antenna is relatively uniform in the horizontal direction and symmetrical in the vertical direction, which is suitable for some communication systems that require balanced feeding.
Higher gain: The gain of the dipole antenna is generally higher than that of the monopole antenna, especially in the vertical direction, which is more symmetrical and can provide a more uniform radiation field.
Wide Frequency Range: Can be optimized for different frequency bands.
Scalability: Can be designed for small devices like IoT sensors or large-scale communication systems.
Dipole Antenna Radiation Pattern
The radiation pattern of a dipole antenna is typically omnidirectional in the H-plane (horizontal plane), meaning it radiates energy uniformly in all directions. However, in the E-plane (vertical plane), it exhibits a figure-eight pattern, with maximum radiation perpendicular to the dipole elements. It always shows as below:
This characteristic makes dipole antennas ideal for applications requiring uniform signal distribution around the antennaâs axis.
Types of Dipole Antennas
1. Half-Wave Dipole Antenna: The most common type, where the total length is half the wavelength.
2. Folded Dipole Antenna: Features an additional conductor for higher bandwidth and impedance matching.
3. Short Dipole Antenna: Uses a shorter length but requires additional tuning for better efficiency.
4. Multi-Band Dipole Antenna: Designed for multiple frequency bands, useful in telecommunications and radar applications.
Applications of Dipole PCB Antenna
Wireless Communication: Wi-Fi, Bluetooth, and RFID systems.
IoT Devices: Smart home automation, industrial sensors, and medical wearables.
Broadcasting: AM/FM radio and television transmission.
Aerospace and Defense: Satellite communication, radar systems, and UAVs.
Automotive: Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.

V-Cut board divisionâ: Cut after extending the board edge, and wiring is prohibited at the cut.
âStamp hole board divisionâ: Separated by a 0.8mm diameter hole array, the hole center is â„1.5mm from the board edge
â3. Routing and power designâ
âLine width calculationâ: Under 1oz copper thickness, line width (mil) = current (A) Ă· 0.024 (such as 1A current requires â„42mil).
âCopper plating stiffener: The LED negative pad is connected to a large area of ââcopper plating (to reduce impedance and assist heat dissipation).
Filter capacitor layoutâ: Each LED is connected in parallel with a 0.1ÎŒF ceramic capacitor (mounting distance â€5mm).
Add 10ÎŒF~100ÎŒF electrolytic capacitors to the power inlet (to suppress low-frequency ripple).
âGround plane divisionâ: Single-point connection between digital ground and power ground to avoid noise coupling.
â4. Thermal management designâ
Heat dissipation hole arrayâ: 0.3~0.5mm diameter through holes (1~2mm spacing) are drilled directly below the high-power LED, and the inner wall of the hole is metallized (to enhance thermal conductivity).
Copper foil area expansionâ: The copper area under the LED is â„ 3 times the pad area (the aluminum substrate can be omitted).
The distance between LED and heating components such as driver IC and MOS tube is â„ 5mm.
Avoid arranging electrolytic capacitors in high-temperature areas.
â5. Design for manufacturability (DFM)â
âPad designâ: The pad size is 0.2mm larger than the LED pin (e.g. LED pin is 1.6Ă0.8mm, and the pad design is 1.8Ă1.0mm).
The solder mask opening is 0.05~0.1mm wider than the pad (to prevent the solder mask from covering the pad).
Polarity markâ: Add a “+” symbol or silk screen frame next to the LED pad (to prevent reverse connection).
Mark point: a solid copper point with a diameter of 1mm is arranged diagonally, and there is no component within 3mm around it. â
â6. Test and debugging reservationâ
Reserve a 30mil diameter circular test point for each LED string circuit (connect to the positive pole of the power supply, ground and dimming signal).
The test point spacing is â„2mm to avoid probe short circuit.
Reserve â„1.5mm channels in dense LED arrays to facilitate hot air gun rework.
7. Design verification and simulationâ
âThermal simulationâ: Use ANSYS Icepak or similar tools to verify the high temperature area (the temperature rise of the aluminum substrate should be â€30â).
âPower integrity simulationâ: Check the power ripple through Sigrity or HyperLynx (target â€5% rated voltage).
âDRC inspectionâ: Focus on checking line spacing (â„0.2mm), aperture (â„0.3mm), and pad and through-hole avoidance (â„0.15mm).
Process markingâ: Clearly specify the solder mask color (white is preferred), surface treatment (immersion gold/OSP), and whether the aluminum substrate needs an insulation layer.
Minimum spacing rule: When SMD layout is in progress, ensuring a certain spacing between components can reduce the probability of problems such as cold soldering, bridging, and shadow effects during welding.
PCB edge requirements: SMD components should not be laid out within 3mm from the two sides of the SMD PCB. This is because the guide groove of the placement machine requires that no components are allowed within 3 to 5mm of the PCB board edge. If this size cannot be guaranteed, consider using V-grooves or stamp holes to lengthen the board, and then remove the excess board after welding.
Arrangement direction: The arrangement direction of the same components should be as consistent as possible, and a test point with a diameter of 30mil must be left on the same gold track. In addition, the arrangement direction of CHIP, SOT, and SOIC components should be perpendicular to the tinning direction as much as possible to avoid shadow effects.
Shadow effect: When wave soldering is used, components with large height differences should not be arranged close together to prevent the shadow effect of high components from affecting the soldering of low components.
Test point requirements: When a right-angle (vertical) arrangement is required, sufficient tinning space must be reserved. The distance of this space should be 0.635mm.
SMD LED PCB Board Design Rules
FAQ of SMD LED PCB Board Design
1. âImproper pad design leads to welding defectsâ
Use “water drop” routing transition to avoid right-angle connection of pads.
Symmetrically design the pad size to ensure balanced heat capacity on both sides.
2. âInsufficient heat dissipation leads to shortened LED lifeâ
Lay a sufficient area of heat dissipation copper foil (â„50mmÂČ/W) under the LED and add heat dissipation through holes.
Aluminum substrate or metal core PCB is preferred for high-power scenarios.
3. âUneven current distribution of parallel LEDsâ
Use star topology wiring to ensure that the length and impedance of each parallel branch are consistent.
Use constant current driver chip instead of traditional resistor current limiting solution.
4. âProcess problems caused by overly dense component layoutâ
Ensure that the LED spacing is â„0.5mm and is more than 3mm away from the board edge.
During wave soldering, adjust the LED arrangement direction perpendicular to the tinning direction, and use a stepped steel mesh to control the amount of solder paste.
5. âPolarity marking error or silk screen blocking the padâ
Clearly mark the LED polarity (such as the “+” symbol), and keep the silk screen away from the edge of the pad by â„0.2mm.
During design verification, check whether the solder mask opening fully exposes the pad.
