A tri-reflector Compact Antenna Test Range (CATR) system which operates at 300GHz is modeled and verified in this work. An efficient Gaussian Beam (GB) analysis method based on point matching expansion technique is proposed to evaluate the predicted quiet zone performance of the CATR system. Experimental result shows that the amplitude ripple within the quiet zone is less than 1.1dB while the phase...
The Compact Antenna Test Range (CATR), which generates a pseudo-plane wave in a very short distance, is commonly employed to measure electrically large aperture antennas for the applications in space remote sensing and radio astronomy. With the increasing operating frequencies, the design of a CATR becomes a technical challenge. This paper presents the designs of two tri-reflector CATRs operating...
