Abstract :
Radiometric instruments with high-gain antennas for space applications in the 200 to 1500 GHz region are under investigation. The measurement of antennas for these kind of applications cannot be made using traditional methods. In this paper, possible methods of measuring large antennas at THz-frequencies, i.e. CATR and near-field scanning techniques are discussed
