In this paper a new shorter focal length design of a Compact Antenna Test Range (CATR) is presented. The new geometry allows the chamber size to be kept about 50% smaller than the geometry of the traditional CATR design. The range we present here has a cubic quiet zone (QZ) of 4.8 x 4.8 x 4.8 m, operating from 0.9 to 18 GHz within a chamber measuring 22 m x 14.5 m x 14.5 m. The design is based on a novel, diagonally fed, short focal length reflector.
