Abstract: A novel directional coupler topology featuring a narrow width is proposed using via-free ridge air-filled substrate integrated waveguide (VF-RAFSIW) technology. The coupler exhibits a 54% ...
Abstract: In this letter, a W-band power combiner is proposed by exploiting the 3-dB branching waveguide directional couplers and GaN power amplifiers. In the framework, a novel waveguide coupler is ...
