Single Layer Transmit-array with Beam-Steering and Polarization Switching

摘要：

　　In this paper,a single layer multi-polarization transmit-array operating at C-Band is designed using ring groove with a single split as the element.The rotational orientation of each element can provide the required phase shift.The elements have identical dimensions,but the rotational orientation of each element is selected to provide a specific transmit-array function.The transmit-array has three working conditions which can change the polarization of the incident wave and set separation beam direction at the same time.The thin single-layer transmit-array without dielectric substrate is designed,simulated and measured based on a horn antenna.The measurement result shows that the transmit-array can switch the linear polarization incident wave to left-circularly polarized wave and right-handed circular polarized wave with separation beam of±30 azimuth angles separately.The measured results are in agreement with the theoretical and simulation results.
