Abstract

In this paper, a single layer multipolarization 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 transmitarray 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 righthanded circular polarized wave with separation beam of ± 30 azimuth angles separately. The measured results are in agreement with the theoretical and simulation results.
