This paper presents a novel technique for realizing a frequency-reconfigurable Fabry-Pérot cavity (FPC) antenna utilizing polarization standing waves (PSWs) and metasurfaces. The antenna's operating frequency can be continuously adjusted within a range of 60.8 - 66.2 GHz, providing versatility for various communication applications. The integration of metasurfaces enables precise control over the electromagnetic field distribution, resulting in a high boresight gain of 22.2 dBi. The experimental demonstration of the proposed antenna at 60 GHz validates the effectiveness of the design approach.
