Radio Anechoic Chamber
The radio anechoic chamber provides a free-space environment for radio wave propagation. It is used for testing radio navigation equipment before field experiments. It is also used for antenna pattern measurement.
The anechoic chamber is built in a shielded box. Its inside ceiling, walls and floor are covered by electromagnetic absorbers, because reducing interference improves measurement accuracy.
