Abstract
An efficient iterative method based on the wave concept is used to analyse Electromagnetic Band-Gap (EBG) structures. It is demonstrated that the integration of EBG structure reduces the unwanted mutual coupling between array elements and interfaces with on board systems. The principle of the iterative method consists of establishing a relationship between incident and reflected waves in order to characterize the studied structure. A technique of coupling pixels-mode is introduced to model vertical connections used in EBG structure. The reflected and transmission coefficients are determined. The numerical results are compared with published data.
