4G Antenna PCB

Working Principle of a 4G Antenna

The working principle of a 4G antenna mainly involves the process of receiving and transmitting wireless signals. As a crucial part of the 4G module, the antenna is responsible for handling wireless signals to enable high-speed data transmission and communication. Its working process are:

  1. Signal Reception: The 4G antenna receives wireless signals firstly from the base station and transmits them to the baseband chip for processing.
  2. Signal Processing: Then the baseband chip decodes and demodulates the received signal, then transfers the processed data to other devices or networks.
  3. Signal Transmission: Next, data generated by the device or application is encoded and modulated by the baseband chip, amplified and filtered by the RF front-end chip, and finally transmitted via the antenna.

Why Does 4G Need Two Antennas?

4G devices use two antennas to get better signal strength, faster speeds, and a more stable connection. This technology is called MIMO (Multiple Input Multiple Output) and helps improve how data is sent and received. By using this technology, the device enables to achieve:

1. Stronger Signal – With two antennas, the device can pick up signals from different directions.

2. Faster Internet Speeds – Two antennas allow the device to send and receive more data at the same time, so users download and upload much faster.

3. More Stable Connection- If one antenna gets a weak signal due to interference or obstacles, the second antenna can still keep the connection steady.

4. Less Delay (Lower Latency) – A dual-antenna setup reduces lag, making activities like video calls, gaming, and streaming smoother with fewer interruptions.

5. Handles More Network Traffic – With two antennas, data moves more efficiently, preventing slowdowns when many people are using the network at the same time.

Simply put, 4G needs two antennas to make internet connections faster, stronger, and more reliable, so users get a better experience wherever they are.

What Cable is Used for a 4G Antenna?

A coaxial cable is commonly used to connect 4G antennas. The best options include:

  • RG58: Suitable for short-range applications.
  • RG174: A thinner cable ideal for compact designs.
  • LMR400: Low-loss cable for long-distance connections.

Does 4G and 5G Use the Same Antenna?

No, 4G and 5G use different antenna with different frequency bands.

  • 4G Antennas: Operate in frequencies from 700 MHz to 2.7 GHz.
  • 5G Antennas: Use higher frequencies, including millimeter waves (24 GHz to 100 GHz).

4G LTE Antenna PCB Design and Layout Rules

1. Maintain Proper Ground Plane Design

  • Use a large, continuous ground plane: A larger ground area improves signal stability and radiation efficiency.
  • Avoid ground plane interruptions: Any cut or split in the ground plane can create unwanted parasitic capacitance and affect the antenna’s impedance matching.
  • Ensure proper grounding of RF components: Connect the antenna’s ground to a low-impedance ground plane for better signal integrity.

2. Optimize Trace Width and Length

  • Keep RF traces as short as possible: Long traces increase resistance and reduce efficiency.
  • Use controlled impedance traces: Maintain a 50-ohm characteristic impedance for minimal reflection and signal loss.
  • Avoid sharp bends in traces: Use curved or chamfered traces instead of 90-degree angles to prevent signal reflection.

3. Place the Antenna in an Unobstructed Area

Keep the antenna at the board edge or corner, avoid placing the antenna near high-speed signals or power components.

4. Maintain Proper Antenna Clearance

Leave at least 5mm to 10mm of clearance around the antenna for best performance. Do not place the antenna too close to the battery or shielding can, as these components absorb and distort signals. For multi-layer PCBs, ensure no traces run directly under the antenna to avoid unwanted coupling effects.

5. Use Proper Via Design for RF Signals

Vias in RF circuits can cause signal loss and interference if not used correctly. Minimize via transitions in RF traces because Excessive vias create unwanted inductance. If vias are required, use multiple vias in parallel is good to maintain signal continuity.

4G LTE Antenna PCB Design and Layout Rules

6. Follow Proper Antenna Matching Techniques

Use a matching network (capacitors and inductors) to fine-tune the antenna to 50-ohm impedance.

7. Consider the PCB Material and Stack-up

Use low-loss PCB materials like Rogers 4350B or FR4 for high-frequency applications. For multi-layer PCBs, separate RF traces from power and signal layers to minimize interference.

8. Prevent Electromagnetic Interference (EMI)

4G antennas PCB design can suffer from EMI due to switching power supplies, digital signals, or nearby RF components. Use shielding techniques like grounded enclosures for noise reduction.

9. Simulate Before Manufacturing

Before finalizing the design, simulate the PCB layout using RF design software like CST Studio Suite, HFSS, or ADS to analyze antenna radiation patterns and impedance matching.
