  • Abstract
    A computer model has been developed in parallel with an experimental study to determine the performance of two offset frequency selective subreflectors, consisting of arrays of concentric rings laid on ABS and expanded polystyrene formers. Radiation patterns in the reflection and transmission modes are compared with those for flat surfaces with the same edge profile, and in reflection with metallic surfaces. The curvature of the subreflectors was small, but still had a noticeable effect on the linear crosspolar patterns in transmission.
