外文摘要：A wideband circularly polarized(CP)aperture-coupled metasurface antenna operating at millimeter-wave frequency spectrum in substrate-integrated waveguide(SIW)technology is proposed.The proposed metasurface antenna is composed of two substrates.The first substrate contains an end-shorted SIW section with a slot etched.The introduced metasurface is printed on the top of the second substrate.The metasurface is comprised of 3 x 3 unit cells,each of which contains two interconnected patches and two parasitic patches.The working mechanism of the proposed metasurface antenna is illustrated in details.The proposed metasurface antenna has wide impedance band-width and axial ratio(AR)bandwidth,which are 66.7％and 40％,respectively.Using the proposed metasurface an-tenna,a 4 × 4 CP metasurface antenna array with an impedance bandwidth of 24％,an AR bandwidth of 30％,and a peak gain of 18.7 dBic in simulation is developed in this paper for millimeter-wave applications.
