A Millimeter-Wave Compact Antenna Test Range Based on Single Reflector

Abstract

A compact field antenna measurement system (CATR) based on a single reflector for millimeter-wave band is designed in this paper, and the design operating frequency range is 26GHz to 110GHz. The diameter of the used rotating parabolic reflector is 410mm, and its edge adopts uniform sawtooth. Ka-band and W-band broadband corrugated horn feeds are designed for the CATR in this paper. It is proved by the system simulation of a typical frequency point that the CATR can form a quiet zone of size 300mmx190mm with phase jitter is lower than 10° and the magnitude jitter is lower than 1dB. The designed CATR system is simple in construction and has excellent electrical performanc.
