Optimization of a Communication Satellite Multiple-Beam Antenna

Abstract

The dimensions of a multiple-beam antenna designed to optimize some desirable characteristics of a synchronous communication satellite are derived. The multiple-beam antenna is an X-band waveguide lens with a cluster of feeds in its focal plane. Two antenna systems are considered: (1) an antenna system radiating pencil beams for area coverage, and (2) an antenna system radiating an earth-coverage beam with nulls in prescribed directions. The characteristics of the optimum configurations are studied over a band of frequency and for practical values of feed excitation errors.
