Abstract
This paper presents a hybrid approach to model the reflector antenna system. A DDM approach is used to model the feed region, and an efficient IE-FFT EFIE algorithm is employed for modeling the sub-reflector, and finally the main reflector is treated using a simple curvilinear PO technique.
