You've got the correct antenna. It supports the correct frequency. But your wireless system continues to underperform. Why?

👉 Antenna positioning is a crucial component that is often disregarded.

In wireless communication, whether in IoT, Wi-Fi, GNSS, or 5G systems, where you position the antenna is just as important as the antenna itself. Let's look at why placement is important and how to get it right.

Why Antenna Placement Matters

Wireless systems rely on radio waves, and antennas serve as signal gateways. Improper positioning can result in:

Signal blocking

Increased interference.

Reduced range and speed.

Unstable connectivity.

Proper positioning results in a stronger signal, longer range, and more dependability.

Five Key Rules for Smart Antenna Placement

1. Avoid Obstructions

Metal, hard plastic, batteries, and even the human body are capable of blocking or reflecting signals.

📌 Tip: Keep antennas away from shielding materials and avoid placing them inside completely enclosed metal enclosures.

2. Keep It Elevated

Height increases line of sight and decreases interference.

📌 Tip: Mount base station or router antennas higher than surrounding objects. Antennas for cars or drones should be placed on the top surface rather than under the chassis.

3. Respect Ground Planes

For PCB antennas, the ground plane functions as an antenna component. A poorly designed layout might have a negative impact on performance.

📌 Tip: To preserve tuning and gain, use the antenna manufacturer's suggested PCB layout requirements.

4. Space Out Multiple Antennas

Running numerous antennas near together (for example, Wi-Fi, LTE, and GPS on the same board) might result in cross-talk and coupling concerns.

📌 Tip: Minimize interference by using correct isolation, distance, and orientation (e.g., perpendicular placement).

5. Test in Real-World Scenarios

Lab testing isn't sufficient. Placement must be confirmed in the final product housing, particularly if the device moves or rotates (as in wearables, robots, or drones).

📌 Tip: Test VSWR, RSSI, and throughput in the final form factor before designing.
