A proposed multiple-beam microwave antenna for earth stations and satellites

An offset Cassegrainian antenna with essentially zero aperture blockage is expected to support closely spaced well-isolated beams suitable for earth stations and satellites. Each beam is fed with a separate small-flare-angle corrugated horn and has good area efficiency over a 1.75:1 bandwidth. Each beam also has good cross-polarization properties. The antenna is compact, and the design appears practical for a 4- and 6-GHz earth station, a 20- and 30-GHz earth station, and a 20- and 30-GHz satellite.
