Single Layer Multi-Polarization Transmitarray in C-Band with Beam-Steering Capability

A single layer multi-polarization transmitarray is presented in this paper, whose structure can be much simpler than the traditional multi-layer frequency selective surface transmitarray. The proposed transmitarray consists of numerous split ring elements and has three working conditions. It is designed, simulated and measured in C-band. The measurement result shows that the transmitarray can switch polarization of the incident wave and set separation beam direction at the same time
