Antenna Measurement Rooms

The pyramidal absorbers are optimised to give the best 'return loss' performance in relation to the wave length.

Overview

The object is for the measurement chamber to mimic free-space via avoiding the reflection of radiated electromagnetic energy (usually Microwave frequencies).

The pyramidal absorbers are optimised to give the best 'return loss' performance in relation to the wave length:

  • -30dB @ 1x wave length
  • -40dB @ 2x wave length
  • -50dB @5x wave length or more.
  • Can reach -60dB return loss by design

The zone of specific interest can be called the quite Zone (or QZ). Contact Global EMC for design help.
