Phase Distribution Analysis of Radiation Pattern of Multi-Beam Satellite Antenna Based on Offset Parabolic Reflector

Abstract:

This paper focuses on GEO multi-beam satellite offset parabolic reflector antenna. In this paper, radiation fields generated by different feeds are derived, and phase radiation pattern is mainly discussed. It can be seen from the numerical results that when the feed is at the focal point of parabolic reflector, the beam has equal phase within beam service area. In addition, for offset feeds, phase changes slowly from beam center to beam boundary, and the variation is about 0.1 radian.
