ABSTRACT:
A TM mode dielectric resonator and a filter comprising such a resonator. The resonator includes metallic walls defining a cavity. A dielectric resonator body is accommodated within the cavity. An end surface of the dielectric resonator body is located in the vicinity of one cavity wall, so as to provide a spacing between said end surface and said cavity wall, at least in a region corresponding to a portion of said end surface. The spacing can be obtained by washers, arranged between the dielectric resonator body and said cavity wall. It can also be obtained by means of a recess in said cavity wall, one or more protrusions on said cavity wall, or a metallic or dielectric ring arranged between the dielectric resonator body and said cavity wall.
