## Abstract A compact design for a singleβfeed cavityβbacked slot antenna is presented for operating at GSM (900 MHz) and DCS (1800 MHz). With the use of a carefully designed power distribution network, a singleβfeed design is realized for a dualβ and wideband slot antenna with high gain and good r
Loading an aperture-coupled ca¨ity-backed slot antenna with a metal post is shown to produce an asymmetrical field distribution in the slot aperture. This field distribution gi¨es rise to a far-field pattern which is directed away from the boresight of the antenna. Theoretical and experimental resul
