Description
Summary:This paper presents a wideband hybrid branch line coupler for millimeter wave applications. The proposed coupler is based on SIW technology and hence has a planar structure. CST microwave studio software is used to simulate and optimize the proposed structure. Simulation results with optimum dimensions show that the proposed SIW coupler has wide bandwidth compared the previous SIW hybrid presented in the literature.
