Compact Size Equal-Length And Equal-Width Substrate Integrated Waveguide Four Channel Power Divider

In this paper a novel broad band substrate integrated waveguide (SIW) power divider is proposed. It consist of four output channels made by SIW with equal length and equal width. Design equations and process are given with mathematical analysis. The propagation constant of the output signals have been adjusted by utilizing only four via in the middle of the output arms. As a result a novel equal output power divider, is obtained accordingly. The experimental results of a prototype at 10GHz shows 3.1 GHz bandwidth in both simulation and measurement results. Return loss and transmission coefficients are in good agreement with simulation results in considered band.
