Advanced Modeling of SIW Structures by 2-D Finite Element Method

Abstract

This paper presents an advanced modeling of Substrate Integrated Waveguide (SIW) structures by 2D vector Finite Element Method (FEM). All types of losses are considered, together with input/output coupling by rectangular waveguide and coaxial cable. Multiple dielectric regions can be defined, allowing the modeling of partially air-filled SIW structures with excellent accuracy and efficiency.
