Characteristics of circular patch on thick substrate and superstrate

Abstract: Accurate formulation for the wall admittance of a circular patch on a thick substrate/superstrate is presented. The principle of equivalence is invoked at the physical aperture of the patch, which yields equivalent electric and magnetic surface currents for the outside fields. The unknown electric current, in terns of the aperture electric field, is obtained from the field continuity condition on the aperture surface. electric and magnetic fields are known. Since there is no tangential electric field on the pa… Show more

“…They deserve special attention because larger bandwidth compared to other conv and outstanding gain -bandwidth chara renders them useful for applications that req and good radiation efficiency, like the communication. Use of parasitic elements e layer or in another layer is a very use improving the bandwidth [1][2][3][4][5][6][7][8][9][10]. The integ more active devices with the patch could b increase the bandwidth of a single-lay antenna.…”
