A Study on Losses in Substrate Integrated Waveguide

Investigation of Losses and Improved Waveguide Method in Substrate Integrated Waveguide for 5G Technology

Abstract

This paper presents different losses associated with Substrate integrated waveguide. As embryonic 5G technology use frequency spectrum from 28 GHz to 100 GHz, which can be achieved using mm-Wave in which frequency ranging from 30 GHz to 300 GHz. But limitations of this mm-Wave include 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.
