Abstract
The present invention relates to a waveguide tuning device () arranged for mounting in a waveguide structure () which has a longitudinal extension (L) and comprises a first inner wall (), a second inner wall (), a third inner wall () and a fourth inner wall. The inner walls are arranged such that a rectangular cross-section is obtained for the waveguide structure. The first inner wall () and the second inner wall () have a first length (b) and are facing each other. The third inner wall () and the fourth inner wall () have a second length (a) and are facing each other. The electrical field (E) is parallel to the main surfaces of the first inner wall () and the second inner wall (). The tuning device () is electrically controllable and arranged for mounting at the first inner wall () and/or the second inner wall (). The present invention also relates to a tunable waveguide structure.
