Miniaturization Trends in Substrate Integrated Waveguide for Microwave Communication Systems

Substrate integrated waveguide structure is an emerging candidate for the components operating within the microwave and millimeter-wave communication system due to its multiple advantages: compact size, low losses, and low fabrication cost. Recently miniaturization of SIW is taking place day by day. In this article, the link of full-mode SIW (FMSIW), eighth-mode SIW (EMSIW), and sixteenth mode SIW (SMSIW) has been presented with their additional advantages. This paper may be a guideline of the analysis of recent miniaturization of substrate integrated waveguides and it can provide a design guideline of microwave components especially in small-size systems.
