Abstract-In this paper, a rigorous and accurate numerical two-dimensional modeling finite element method 2D-FEM is applied to the analysis and design of substrate integrated waveguide components. The finite element method represents an excellent tool for the analysis and design since it easily allows taking into account all details of each device. The advantages of this method have been proved with the successful design of two SIW waveguide topologies operating in [8][9][10][11][12] GHz and [10.7-12.75] GHz respectively for X-band and Ku-band applications employed in satellite communications. In order to validate the proposed method, a comparison is made between the FEM method implemented in Matlab and CST Microwave Studio

“…Recently, several techniques have been proposed that may significantly shorten the design and optimization process. In [10] the Boundary Integral Resonant Modes Expansion (BIRME) has been adapted to analyze efficiently post walled structures, in [11][12][13] SIWs have been analyzed considering only the presence of the parallel plate waveguide (PPW) TEM mode and taking into account the scattering by the metallic posts, so reducing the analysis to the solution of a two dimensional problem. In [14] the authors presented a technique based on the full dyadic Green's function of the parallel plate, expressed as series of vector wave functions [16] TE and TM with respect to the waveguide height.…”

Abstract-In this paper, a full-wave analysis technique of lossy substrate integrated waveguides, based on the dyadic Green's function of the parallel plate waveguide, is presented. The field inside the waveguide is expressed in terms of cylindrical vector wave-functions and the finite conductivity of the top and of the bottom plates, and of the metallic vias are taken into account. Losses into the dielectric substrate are also included. Coaxial ports are considered as sources and self and mutual admittances are evaluated. Cases of practical structure taken from literature are presented showing a very good agreement with the most used commercial software.

“…a waveguide whose modes are known analytically. In [6], the ports of the problem are characterised by means of a single current formulation; in other formulations [7] the ports are solved using both electric and magnetic currents. Thanks to this simplification, the weights of the scattered modes become unknowns of the resulting system of equations; this fact is exploited to achieve certain efficiency improvement.…”

“…In this paper a fully modal characterisation of the ports is proposed, in opposition to the traditional two currents based approach of [7] or the single current based approach of [6]. This fully modal characterisation of the ports produces smaller systems of equations, so an additional efficiency improvement is achieved.…”
