Abstract

This paper focuses on the analysis of passive devices using a recent emerging technology named Substrate Integrated Waveguide (SIW). This technology has been used in the conception of planar compact components for the microwave and millimeter wave’s applications. Through using Ansoft HFSS and CST code a substrate integrated waveguide coupler has conceived and optimized in this study. The SIW 90° coupler design simulations show good performances with low return loss, high isolation better than -20 and -40 dB, respectively and broad operational bandwidth.
