Nonleaky conductor-backed coplanar waveguide-fed rectangular microstrip patch antenna

A new arrangement for exciting microstrip patch antennas is presented here that allows easier integration with monolithic microwave integrated circuits (MMIC's). The non-leaky conductor-backed coplanar waveguide (NL-CBCPW) is described with emphasis on avoiding the leakage of power. This structure is utilized for feeding a rectangular patch through an aperture in the back plane. The full-wave analysis of this arrangement was carried out using the moment method in the spectral domain. The theoretical and measured results of such a patch are given.
