Abstract
In this paper, a polarization and frequency reconfigurable antenna with double layer metasurface, responsible for frequency and polarization reconfiguration respectively, is proposed. This antenna could operate in linear polarization in 4â¯GHz and circular polarization in 5â¯GHz band. By rotating the frequency reconfiguration metasurface, the linear polarization (LP) operating frequency can be continuously changed from 4â¯GHz to 4.35â¯GHz (8.4%) with circular polarization operating frequency around 5â¯GHz unchanged. Moreover, polarization of the whole antenna at 5â¯GHz can be reconfigured to linear polarization (LP), right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) by rotating polarization reconfiguration metasurface, the 3â¯dB axial ratio bandwidth is 5.0-5.2â¯GHz (4%). In all states, gain of the antenna achieves 5 dBi.
