Abstract: 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. This paper presents the designs of two tri-reflector CATRs operating at 200 GHz: a Cassegrain-Gregorian (CG) configuration and a Double Gregorian (DG) one. Both of the two designs utilise two shaped sub-reflectors and a spherical main reflector. The characteristics of the two designs were verified using a commercial package GRASP9.
Keywords: Compact Antenna Test Range, Tri-reflector, millimeter/sub-millimeter wave.
