Design and Analysis of a Reflector Antenna System Based on Doubly Curved Circular Polarization Selective Surfaces
This paper discusses the design and analysis of a reflector antenna system combining two doubly-curved Circular Polarization Selective Surfaces to provide a functionality equivalent to that of a dual gridded reflector but in circular polarization. The key feature of this design is to use a non-resonant CPSS design to avoid the bandwidth limitation of most CPSS designs previously discussed in the literature. A specific design at Ku-band is investigated and promising results are demonstrated, providing a cross-polarization discrimination higher than 25 dB over the full band.
