| Summary: | International Telemetering Conference Proceedings / October 13-15, 1981 / Bahia Hotel, San Diego, California === A microstrip antenna feed developed for a paraboloidal reflector provides simultaneous
right circular and left circular polarization and 20 dB sidelobe levels over moderate
bandwidths. This arrangement obviates the need for the usual waveguide orthomode
transducer and thus decreases the weight of the feed. The basic feed element is a square
patch .558λ x .558λ fed at two orthogonally situated coaxial feed points inset 0.118λ from the
edge, as described by Millar and Carver (Proceedings 1980 University of Illinois Allerton
Antennas Application Symposium). |
