A novel design of printed ridge gap waveguide‐based 0‐dB backward‐wave coupler

This article presents the design and implementation of a 0‐dB coupler based on Gap Waveguide (GW) technology. The proposed coupler is considered as the first backward‐wave 0‐dB realized using this technology. It operates at a central frequency of 30.5 GHz and maintains good performance regarding iso...
