For the correct analysis and design of devices like couplers, filters or antennas an accurate model for the characterization of SIW is needed. In this contribution a new model for electromagnetic characterization of SIW is proposed. The model is based on the analysis of a closed waveguide, which simulates the behavior of an open structure. For the correct simulation of the open structure a dielectric material is adjusted. Finally a pass-band filter in SIW technology is analyzed in order to verify the proposed model.}, author = {C A Leal-Sevillano and J A Ruiz-Cruz and Montejo-Garai, J R and Rebollar, J M} }
