[Poster Presentation] Proposal of a Simplified Design Model for Substrate Integrated Waveguide

Abstract (in Japanese) (See Japanese page) 
(in English) In the millimeter wave band, radiation loss in transmission lines is a major issue. Substrate Integrated Waveguide (SIW) has a structure in which vias (metal-plated through holes) are arranged in a dielectric substrate, and realizes characteristics equivalent to those of a rectangular waveguide. It can reduce radiation loss compared to open-type lines such as microstrip lines. The vias of SIW, which simulate the side walls of a rectangular waveguide, are different from flat plates, so the radius and spacing of the vias must be designed. Previously, eigenvalue analysis has been proposed to design vias by analyzing the Floquet mode of one period of SIW so that the phase constant is the same as that of a rectangular waveguide. However, the analysis is complicated for practical design. In this presentation, we propose a simplified analysis model to design vias so that the reflection coefficient of the TEM wave perpendicularly incident on the side wall of the waveguide matches the reflection coefficient from SIW via. In order to verify the proposed method, we analyzed a model in which a lossless rectangular waveguide was connected to a 1 mm-long SIW in the 300 GHz band. As a result, good propagation characteristics were confirmed with a reflection coefficient of less than -30 dB, a transmission coefficient of more than -0.005 dB, and a phase difference of -0.9°.
