Performance Comparison between Trapezoidal and Triangular Serrated Compact Antenna Test Ranges with Smooth Transition at the Corners

Abstract

This paper presented a theoretical and numerical assessment trapezoidal and triangular serrated Compact Antenna Test Range (CATR) The CATR provides uniform illumination within the Fresnel region to the test antenna. The performance comparison between trapezoidal and triangular serrated edge compact range reflector with Smooth Transition at the Corners (STC) are investigated. Application of serrated edge has been shown to be a good method to control diffraction at the edges of the reflectors. In this paper the Fresnel fields of trapezoidal and triangular serrated CATRs with STC are analyzed by the Physical Optics (PO) techniques. It is observed that trapezoidal serrated CATR gives ripples free and enhanced quiet zone width than triangular serrated CATR.
