ANTENNA DECOUPLING
Anechoic chambers are controlled environments designed to eliminate reflections of electromagnetic waves and to enable precise, reproducible measurements of electronic and RF systems, while also providing a free‑space testing environment.
how it works
An anechoic chamber is a Faraday cage with pyramid-shaped absorbing materials covering the conductive walls. These structures absorb waves, eliminate interference and echoes, but also prevent reflections and refractions, while simulating an infinite space around the RF system to enable precise measurements.
USE CASES
Wireless communication devices
Evaluate the performance of devices such as smartphones, Wi-Fi routers, antennas and IoT devices, measuring their radiation and sensitivity without external interference.
R&D
Design and optimization of antennas and sensors in free-field conditions, without reflective interference.
Conformity test
Checks that devices comply with regulatory standards for electromagnetic emissions and susceptibility.
