Design of Polarization Reconfigurable Antenna Based on Rotatable Metasurface

A planar slot antenna with the reconfigurable property of polarization is introduced in this paper. The polarization reconfiguration can be achieved by using a metasurface (MS) consisting of 16 elements with a rectangular configuration, which can be rotated to realize three polarizations states- left-hand circular polarization (LHCP), linear polarization (LP) and right-hand circular polarization (RHCP). To present the advantage of the proposed configuration, this antenna is fabricated and measured. The measurement results show that the performance of the MS antenna in impedance bandwidth, axial ration bandwidth (ARBW) and gain is better than that of original antenna.
