Losses in ridge gap waveguide compared with rectangular waveguides and microstrip transmission lines

Abstract

A study and quantification of losses in ridge gap waveguide, compared to losses in ideal standard rectangular waveguide and microstrip transmission line is presented. The study is performed by evaluating the quality factor of resonators made of ridge gap waveguide, rectangular waveguide and microstrip line. Results will show that the ridge gap waveguide has a very low loss.
