Measurement techniques for cryogenic Ka-band microstrip antennasThe measurement of cryogenic antennas poses unique logistical problems since the antenna under test must be embedded in the cooling chamber. A method for measuring the performance of cryogenic microstrip antennas using a closed cycle gas-cooled refrigerator in a far field range is described. Antenna patterns showing the performance of gold and superconducting Ka-band microstrip antennas at various temperatures are presented.
