Abstract

In this paper, an accurate analysis method of substrate integrated waveguide based on mode matching technique is presented. The structure is approximated by consecutive rectangular waveguides. A unit cell structure is analyzed by considering field distribution as the summation of TE_n0 modes in rectangular coordinate system. Due to the periodicity of the structure, the propagation characteristics of substrate integrated waveguide modes can be deduced from investigating of the unit cell and employing Floquet theory. Finally, through comparison between our results with other published results, accuracy of the proposed method is verified.
