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.
