Abstract

The performance of circular polarization selective surfaces (CPSS) under oblique incidence is examined experimentally. A fabricated CPSS prototype working around 10GHz has been characterized under oblique incidence ranging angles between ±30°. It was found that increasing the angle of incidence, the frequency at which minimal axial ratio (AR) is achieved deviates from the resonant frequency of the CPSS, resulting in higher AR within a given bandwidth. Design guidelines will be given in order to minimize this limitation.
