            Abstract : 
This paper presents the performance of a new Circular Polarization Selective Surface (CPSS) that has the 2-fold rotational symmetry that is theoretically required for an improved performance under oblique incidence. Comparison between the simulation results for Pierrot´s CPSS design that does not have that symmetry, and the results for the new design shows the improved performance of the new design. Further improvement comes from optimizing the inter-element spacing.
