Abstract
Describes some aspects of the antenna measurement range design and measurements of electrically large antennas using a centre frequency of 183.3 GHz. The test antenna is an offset Cassegrain system with a main reflector providing an aperture of approximately 200 mm diameter and is fed using a corrugated feed horn. The half power beamwidth is 1.1°±10% and it is also desired to measure the antenna radiation patterns with a dynamic range of better than 60 dB
