Application of Compact Antenna Test Range in Terahertz Antenna Measurement

摘要

This paper demonstrates the application of compact antenna test range (CATR) in the field of terahertz antenna measurement engineering. The existing 1m aperture tri-reflector CATR system is proposed in the paper. This system is applied to measure several terahertz antennas. Besides, the simulated 5m aperture tri-reflector CATR with a 70% aperture efficiency is demonstrated with consistent amplitude and phase performance in a quiet zone at 300GHz.
