Dual Gap Wideband In-Phase Power Divider Based on Ridge Gap Waveguide Technology

Power dividers are critical components for mm-wave applications. They are used in antenna feeding structures to provide the suitable excitation in the antenna array systems and deployed in microwave smart beam switching subsystems. In this article a dual gap wideband in-phase power divider is presented. The bandwidth starts at 19 and ends at 40 GHz. We are targeting with this design both the k and ka bands. The proposed design achieved a very deep matching level below −18 dB.
