摘要：
This paper presents a low-profile single-layer metasurface antenna with reconfigurable polarization ability. The proposed design consists of 3 x 4 rectangular metasurface elements and a coplanar waveguide feeding line (CPW) which are all lying on the same substrate. The polarization reconfigurability is achieved using pin diodes that are embedded in the coplanar waveguide feeding line. Therefore, the antenna can operate in three modes: linear polarization (LP), right-handed circular polarization (RHCP), and left-handed circular polarization (LHCP). The simulated results show an impedance bandwidth (IBW) of 6% (5.55-5.9 GHz) in LP state and 17.4% (5.55-6.6 GHz) in both LHCP and RHCP states and a 3-dB axial ratio bandwidth (ARBW) of 113% (5.63 - 632 GHz).
