Abstract :
In this paper, the impact of the structure scattering between the horn and subreflector of a Cassegrain reflector antenna system has been presented. Typical design steps involve (1) feed design that has very good VSWR and (2) use the far field pattern to compute the illumination on the subreflector and subsequently the main reflector to determine the far field pattern of the whole antenna system.
