Transition arrangement for a transition between two ridge gap waveguides

Abstract

A transition arrangement (100) comprising a first conductive layer (110), a second conductive layer (120), and a third conductive layer (130) in a stacked layer configuration. The first conducive layer (110) comprises a first ridge (111) arranged along a first waveguiding path, and a first metamaterial structure (113) arranged along a perimeter of the first waveguide path. The second conducive layer (120) comprises a second ridge (121) arranged along a second waveguiding path, and a second metamaterial structure (123) arranged along a perimeter of the second waveguide path. The third conductive layer (130) is arranged in between the first and the second conductive layers (110, 120). The third conductive layer comprises respective planar surfaces facing the first and the second first metamaterial structures (113,123), respectively. The third conductive layer comprising an aperture (131) arranged in connection to the first and the second ridges (111,121) to couple electromagnetic waves between the first and the second ridges. The first and/or the second ridge (111,121) comprises a respective ridge matching section (112,122) in connection to the aperture (131) and preferably facing the aperture.
