Design and analysis of substrate integrated waveguide (SIW) for high frequency applications

Abstract

In this paper, substrate integrated waveguide has been designed and analyzed for high frequency applications. As high frequency suffers attenuation due to metal waveguide, atmospheric attenuation and Rain fade etc.A improved waveguide method is adapted known as Substrate Integrated Waveguide. SIW is transition between micro-strip antenna and Dielectric filled Waveguide antenna. SIWs are planar structures so they can be fabricated over PCBs and can be easily integrated with supplementary transmission lines. In the study, the different parameters like electric field generated, transmission gain and return loss is evaluated. Results are calculated over a frequency ranging from 6 GHz to 11 GHz.
