Abstract

Auxiliary defocused feeds with weak excitation can be used to cancel or reduce specific near-angle sidelobes of double reflector antennas. Existing earth terminals may be upgraded in this way to provide improved isolation between interfering satellites when the tight station-keeping tolerances agreed at WARC-79 come into force.
