A new technique for reducing the substrate permittivity in a Substrate Integrated Waveguide (SIW) structure is presented, consisting of removing a centered rectangular box of substrate dielectric material, which increases the equivalent waveguide impedance. This technique can be applied to the implementation of high-impedance SIW sections (perforated regions) sandwitched between low-impedance sections...
A novel ridge substrate integrated waveguide (RSIW) with extended single-mode bandwidth is presented in this paper. The proposed structure is based on a substrate integrated waveguide including two dielectric layers with different permittivity. The ridge is implemented by a row of partial height metal vias, connected at the bottom by a metal strip. An RSIW with cutoff frequency of the fundamental...
