Abstract
This paper presents the mathematical model of the offset parabolic reflector antenna and analyzes it based on aperture-field method. It is convenient and efficient to calculate the radiation characteristics of the offset parabolic reflector antenna with multi-feed placed arbitrarily. Then,the position of the feed is modified based on the concept of beam optimization to meet the design requirements. Finally,the multi-beam offset parabolic reflector antenna is designed. Revolve the feed array around a certain axis,more space can be scanned.
