مستخلص: | This communication reports the dual circularly polarized high-aperture-efficiency transmitarrays (Tas) capable of forming patterns with two independent beams for the right-hand circularly-polarized wave (RHCPW) and left-hand circularly-polarized wave (LHCPW) at the same frequency. The five-layer TA elements contain a ring-slot resonator loaded by interdigital capacitors in each layer. The TA element was optimized as a three-bit phase shifter that adds two independent phase shifts to the transmitted RHCPW and LHCPW. The geometry of the TA element was validated by designing two 500-element TAs. At 36.5 GHz, these two TAs form RHCP beams in the directions |
