ABSTRACT:
A multimode composite resonator, in particular for a microwave filter, includes a resonant cavity, a dielectric resonator element disposed inside the cavity, a tuning element for each mode and a coupling element for coupling between modes. The resonator element is shaped to have plural vertices which are short-circuited together by the conductive walls of the cavity via direct or RF electrical contact between the vertices and the walls. Various geometrical resonator shapes are possible.
