معرفی ساختار های SIW

1. Introduction

In high frequency applications, microstrip devices are not efficient, and because wavelength at high frequencies are small, microstrip device manufacturing requires very tight tolerances. At high frequencies waveguide devices are preferred; however their manufacturing process is difficult. Therefore a new concept emerged: substrate integrated waveguide. SIW is a transition between microstrip and dielectric-filled waveguide (DFW). Dielectric filled waveguide is converted to substrate integrated waveguide (SIW) by the help of vias for the side walls of the waveguide.

Figure 1: (a) Air filled waveguide, (b) dielectric filled waveguide, (c) substrate integrated waveguide

Because there are vias at the sidewalls, transverse magnetic (TM) modes do not exist; TE₁₀ therefore is the dominant mode. There are many articles for designing substrate integrated waveguides, however there are missing parts in many of them, they just give the known equations but they do not carefully investigate those equations. In this report, the tolerances of the published SIW design equations are inspected.
