Dual Frequency and Dual Polarization Beamforming based on Tensor Impedance Metasurface

In this paper, a dual frequency and dual polarization beamformed metasurface based on impedance superposition algorithm and metasurface partition method is proposed. The designed metasurface can achieve a pitch angle range of (-15°, 15°) for spherical beam and (-25°, 25°) for flat-topped beam. The frequency and shaped beam switching can be realized by switching the feed sources, which provides a reference for wireless communication detected by multi-frequency and wide-angle radar.
