Resemblance Between Gap Waveguides and Hollow Waveguides
Artikel i vetenskaplig tidskrift, 2013

There is a lack of suitable numerical ports for the gap waveguides. This study studies the resemblance between the ridge/groove gap waveguide and the conventional hollow ridge/rectangular waveguide, respectively, by using numerical analysis. The dispersion diagrams and characteristic impedances are compared and found to be similar within the stopband of the parallel-plate modes. Therefore conventional hollow waveguides can be used as ports in numerical analysis of gap waveguides. In addition, this means that the geometry of circuit components in hollow ridge/rectangular waveguides can be used as a good starting point when designing ridge/groove gap waveguide components.
