Compact Range Chambers
A Compact Range makes direct far-ﬁeld measurement of electrically large antennas in a shielded anechoic chamber. It uses a large parabolic reflector to project a small radiating source (feed) into the far ﬁeld. Multiple-feed systems may be used to improve the far-ﬁeld charac-teristics. The system also allows system level testing of the complete device architecture.
