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