Abstract
It is shown that for small and medium-sized circular symmetric reflector antennas it is very important to include the effect of the multiple scattering between the feed and the reflector when determining the secondary pattern. In particular, when corrugated soft surfaces are used to improve the polarization characteristics of primary feeds, the corrugations will cause very high cross-polarization due to multiple scattering. This is very well predicted by the multiple scattering approach.<>
