Abstract: A waveguide transition includes a ridge waveguide section with a first ridge part running along a first wall having a first distance to an opposing second wall. The waveguide transition comprises a partial H-plane waveguide section with an electrically conducting foil that comprises a longitudinally running foil slot ending a certain edge distance before a foil edge that faces the ridge waveguide section. The ridge waveguide section and the partial H-plane waveguide section overlap during a transition section that has a first end at a transition between the second wall and a third wall. There is a second distance between the first wall and the third wall that exceeds the first distance. The transition section has a second end where the first ridge part ends by a transversely running second ridge part that crosses the foil slot and connects to a third wall.

Abstract: The present invention relates to a tuneable waveguide structure comprising a first, second, third and fourth electrically conducting inner wall. The first inner wall and the second inner wall are facing each other, and the third inner wall and the fourth inner wall are facing each other, the intended extension of the electrical field is parallel to the first inner wall and the second inner wall, and perpendicular to the third inner wall and the fourth inner wall. The waveguide structure comprises at least one tuning device that comprises a wall part that is movably arranged along an extension that is perpendicular to the intended extension of the electrical field. Each wall part is at least indirectly connected to support rods that are in sliding engagement with a corresponding sloped surface that is laterally adjustable in the extension of the slope. Each wall part may be constituted by an electrically conducting foil.
