A Circular Polarization Selective Surface for Space Applications

In this paper, an LHCPSS based on the Pierrot cell has been theoretically studied and demonstrated experimentally. Design guidelines are given and an accurate fabrication process has been developed. Measurements of a fabricated prototype exhibit performance compliant with the requirements for space applications over a limited bandwidth. Axial ratio and insertion loss smaller than 1 and 0.5 dB, respectively, over a 7% bandwidth have been achieved at 9.8 GHz. Wider bandwidths with low axial ratio are possible by relaxing the requirements in terms of insertion loss.
