Abstract

In this paper, rigorous Mode-Matching Technique (MMT) with Generalized Scattering Matrix Method (GSMM) is used to analyze novel hybrid SIW coupler operating at 26 GHz for 5G applications. The introduced coupler has an equal-amplitude of about -3 dB besides 90-degree at its forward and coupled output ports with more than 4 GHz bandwidth. In addition to rigorous analysis, full-wave CST simulator is used to optimize coupler structure and the results from MMT and CST are compared and discussed. The coupler structure divided into two symmetrical cascaded parts with each part having multi-port bifurcated sections. Due to symmetrical structure, analyzing one half of the coupler with MMT has been sufficient for full analysis.
