  • Method of producing a dual reflector antenna system
    Patent number: 5160937
    Abstract: A dual reflector antenna system capable of passing radiation to or from a shaped coverage area by means of a single feed, a three dimensional main reflector surface and a three dimensional subreflector surface. Desired levels and/or characteristics of radiation incident upon or received from selected regions of said coverage area are defined, and actual radiation levels and/or characteristics for said regions by modifying both said reflector surfaces are optimized simultaneously. The optimization is achieved by iteratively determining levels and/or characteristics of radiation incident upon or received from each of said regions and obtaining the least favorable value of level and/or characteristic and modifying said reflector surfaces simultaneously to obtain an improved least favorable value of level and/or characteristic.
