Abstract :
Resonance characteristics of cylindrical-rectangular patch resonator in the presence of a laminated ground plane are studied. The laminated ground is modelled by a cascaded transition matrix in the spectral domain. An integral equation is formulated in terms of the surface current on the patch. Galerkin´s method is then applied to solve for the resonance frequency. Factors analysed include substrate thickness, substrate dielectric constant, and laminate conductivity. It is found that certain laminate conductivities cause more power loss than the others. Replacing a perfect conductor ground by a laminated composite may shift the resonance frequency by 10%
