In this paper, a frequency and polarization reconfigurable antenna composed of a planar slot antenna, a metallic reflector and a metasurface have been proposed. The double slot structure is used in the planar slot antenna to extend the bandwidth of the antenna. The relative distance between the metasurface and the planar slot antenna can be adjusted to achieve the frequency and polarization reconfigurability of the antenna. The gain of the antenna is also improved due to the presence of metasurface on the top of the substrate. To verify this, a frequency and polarization reconfigurable antenna is designed using HFSS (high frequency structure simulator). The simulated result shows that the frequency and polarization reconfiguration can be achieved from 7.2GHz to 11.5GHz. The polarization of the antenna can be reconfigured from linear to left hand circular polarization (LHCP) and right hand circular polarization (RHCP). The maximum gain achieved by the proposed frequency and polarization antenna is 15.5dB.
