Abstract

The performance of offset Cassegrain antennas shaped to provide wide scan angles, is outlined for use in earth stations which are capable of accessing several satellites simultaneously. The effect on the beam efficiency of scanning over a rectangular-shaped coverage region located about the geo-stationary arc is described. Limitations on scan performance are discussed as is the effect of satellite tracking by feed movement.
