Microwaves101 | Substrate Integrated Waveguide Substrate Integrated Waveguide (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... Flat Waveguide with a Longitudinal Slot Multilayered or stacked substrates and vias for suppressing leakage into the substrate are less well fabricated in practice.This paper presents an analysis of a flat waveguide with a longitudinal slot, reports new theoretical findings, illustrates characteristics of the line and predicts its applicability.
