A simple circular polarization selective surface (CPSS)

A new circular polarization selective surface (CPSS) (a surface that reflects one sense of circular polarization but transmits the other) is described. It is easy to fabricate and has excellent electrical characteristics. This CPSS element is made of a single piece of wire bent in three sections. The two end sections are on the faces of a dielectric slab and the middle section goes through it. This resonating element does not use transmission lines, and printed circuit technology can be used for fabrication above a few gigahertz. Results of a simulation of a 25-element CPSS are presented. Preliminary experimental results confirmed the theoretical findings.<
