RF Assessment of the Mechanical Design of the Compact Antenna Test Range for HERTZ 2.0

Abstract—The Compact Antenna Test Range (CATR) for the HERTZ 2.0 measurement facility at the European Space Agency was electrically designed to meet the geometrical and RF requirements set by the Agency. The CATR is constituted by a 18.5 m x 16.1 m serrated parabolic main reflector and a 15.2 m x 14.4 m serrated hyperbolic sub reflector achieving a quiet zone (QZ) of 5 m in L band. The reflectors have then undergone a detailed mechanical design to ensure their practical fabrication and installation. In this paper we present the electrical effect in the QZ of the chosen mechanical implementation.
