Abstract

The paper presents a new equivalent circuit model for electromagnetic bandgap structures embedded in a parallel-plate wave-guiding environment in a 2D fashion. The model, based on the transmission line theory and periodic structures, by employing a simple lumped-element substitute for the patch-via structure, presents a first order, but detailed, quantitative and qualitative analysis of the filtering properties of the metallo-dielectric electromagnetic bandgap structure. Comparison of results derived from this model and numerical modeling, shows that this model is able to describe the resonant properties of the structure as well as its pass-band and stop-band regions with enough accuracy to make it a useful tool as the first step in the design of the structures under consideration.
