Circular polarization selective surface for dual-optics CP offset reflector antennas in Ku-band
The design of dual-optics circular-polarization offset reflectors has been addressed by using circular polarization selective surfaces (CPSS). A novel design of CPSS based on Pierrot's cells is proposed, and design guidelines and limitations of this technology are given. Manufacture constraints are discussed and a more reliable fabrication process is developed. A 29×29 array has been constructed and measurements are ongoing.
