Abstract

The satellite broadcasting in the 21-GHz band is expected to transmit large capacity programs. We have proposed an array-fed imaging reflector antenna which is effective to exploit the limited resources because of its ability to control radiation pattern. An antenna configuration for engineering test is introduced. We evaluated radiation patterns affected by thermal distortion on the reflector and control error in the beam forming network.
