Abstract
A low-profile wideband circularly polarized reconfigurable metasurface antenna is proposed. The proposed antenna consists of a 3 × 4 rectangular metasurface element (MTS) and a rotated coplanar waveguide feeding line (CPW). Four PIN diodes (D1, D2, D3, and D3) are utilized to realize circular polarization reconfigurability. The antenna could operate in left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP) depending on the state of the diodes. The simulated results show an impedance bandwidth (IBW) of 16% and a 3-dB axial ratio band (ARBW) of about 13% in both RHCP and LHCP radiation modes, while the gain for both polarizations is higher than 6 dBi in the operating band.
