Full Anechoic Chamber
The full anechoic chamber is used to measure antenna radiation patterns. The frequency range of operation of the chamber is from 600 MHz to 26.5 GHz. It includes a spherical near-field system with a “roll over azimuth” L-bracket positioner for the Antenna-Under- Test (AUT) and a probe stand (as seen in ‘Chamber Layout’). An antenna measurement software is available for spherical near-field and quasi-far-field measurements.
The measurements are done inside a room with electromagnetic shielding. Additionally, the walls, ceiling, and floor of the interior are lined with specially treated pyramidal foam absorbers that prevent reflection of the electromagnetic and thereby emulating a free- space propagation environment. While mainly intended for antenna radiation pattern measurements, the chamber can also be used for other electromagnetic and radio frequency experiments or tests.
