Abstract
A microwave resonator, in particular for a filter, comprising a resonant cavity having positioned therein a plane resonator element, frequency tuning means, and intermode coupling means, the resonator element being made of a dielectric material that is at least approximately in the shape of a parallelogram and being disposed transversely in the cavity in such a manner that the vertices of the parallelogram are short-circuited to one another by the conductive inner wall of said cavity. The resonator has at least one other plane resonator element made of dielectric material in a shape that is at least approximately that of a parallelogram, the resonator elements being placed close together, mutually parallel, and extending transversely to a central axis of the cavity. The frequency tuning means and the intermode coupling means are positioned between the parallel resonator elements.
