摘      要：We introduce a dual-polarized(DP)Fabry–Perot cavity(FPC)antenna operating at the millimeter-wave(mmWave)frequency band with high-gain and wideband characteristics.A DP feeding source and a partially reflective surface(PRS)integrated with a Fresnel zone lens are suggested to realize dual-polarization wave radiation over a wide impedance *** feeding source provides vertical and horizontal polarizations while keeping high isolation between the two *** is used to realize Fabry cavity to produce a directive beam *** integrated Fresnel zone rings are introduced for phase correction,leading to a significant gain enhancement for the *** verification,a 60-GHz FPC antenna prototype with DP radiation is designed and fabricated with measurement *** consists of a feeding source,a PRS integrated with a Fresnel zone lens,a quasi-curved reflector,and four three-dimensional printed *** results illustrate that the peak gains of vertical and horizontal polarizations are 18.4 and 17.6 dBi,*** impedance matching bandwidth for the two polarizations is 14%.The performance ensures that the proposed DP FPC antenna is a promising candidate for the fifth-generation wireless communication systems in the mmWave band.
