Planar groove gap waveguides
… planar medium to achieve this integration is the Substrate Integrated Waveguide (SIW). However, due to a lack of DC isolated planes of the structure, bridging wires or concentric etched rings are often used to enable active device biasing. This research presents a novel planar structure referred …
