An anechoic chamber (“an-echoic” meaning non-reflective, non-echoing or echo-free) is a room designed to completely absorb reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The combination of both aspects means they simulate a quiet open-space of infinite dimension, which is useful when exterior influences would otherwise give false results.
In the RF world, the reflective walls of the shielded room are made “invisible” or “anechoic” by covering them with RF absorbing materials. The most common absorber is a carbon loaded foam pyramid. Sharp tips on the absorbers keep RF waves from bouncing off, allowing the waves to slowly transition from air to the lossy carbon inside of the foam. This gradual taper from tip to core is the secret to RF absorbers. The amount of RF that bounces off of anechoic chamber walls is often 0.1% to 1% (-30 to -20 dB) of the original wave. The low level of reflections in our chamber allow us to accurately measure your antennas gain, efficiency, and radiation patterns
Broadband Pyrimidal Absorbers and Broadband Wedge Absorbers are available from 4″ to 96″. Ferrite absorber is available in flat tile ranging from 5.4 to 6.7 mm thick and grid type is available in 19mm x19mm. Both are 100mm x 100mm.
