      <Abstract>In this paper design of a low-profile frequency reconfigurable metasurface (FRMS) antenna has been proposed. The proposed FRMS antenna consists of a simple rectangular patch antenna (source antenna) having circular ground plane of radius 20 mm and a circular metasurfaceof same radius. The metasurface is palced directly over the patch to make the FRMS antenna very compact with a total thickness of 3.048 mm. The metasurface consists of rectangular loop unit cells arranged uniformly along the vertical and horizontal directions. Simulation result shows that the antenna can be tuned by rotating the metasurface around the center of the patch antenna. Rotation of metasurface results a change in relative permittivity and relative permeability of the structure and the resonant frequency of the FRMS antenna. The proposed antenna has been designed on Ticonic RF-35 substrate with a dielectric constant of 3.5 and thickness of 1.524 mm. The antenna parameters like gain, return loss, radiation pattern and efficiency are analysed using HFSS. The proposed antenna resonantsfrom 4.5to 6 GHz. The antenna is suitable for various wireless communicationapplications such as WLAN band (5.180- 5.825 GHz), ISM band (5.725-5.875 GHz) and so on.</Abstract>
