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.

Dielectric resonator for a microwave filter, and a filter including such

A filter having a dielectric resonator, the filter comprising at least one cylindrical cavity (10) containing a cylindrical dielectric resonator (11) whose axis of symmetry (.DELTA.) is colinear with the axis of said cavity (10), and the resonator being held in a longitudinally asymmetrical position inside said cavity (10) by a mandrel system which clamps around the cylindrical portion thereof and which includes at least one spoke for fixing it to said cavity while leaving play relative to said cavity.
