摘要: A dual-mode circular polarization selective surface (CPSS) cell based on a modification of the Pierrot is presented for single-layer dual-band circularly polarized (CP) reflectarray antenna design. To achieve CP discrimination performance, improved three-dimensional geometry and high-order resonances CPSS are utilized. The required phase shifts in both modes obtained by varying rotation angle. operating with orthogonal CPs has been fabricated tested. Measured results show peak gains 25.2 dBi at 11.6 GHz 31% 3 dB axial ratio (AR) bandwidth 26.5 dBi 14.6 GHz 32% AR bandwidth, respectively. measured efficiency 41.2% 55.5% 14.6 GHz.
