ABSTRACT:
A compact dielectric coaxial resonator is provided which includes a dielectric substance having a preselected length along the center line thereof, a groove formed in an end portion of the dielectric substance, a through hole, formed in the dielectric substance, extending through the center line of the dielectric substance, an outer conductive member provided around the periphery of the dielectric substance, and an inner conductive member provided over the groove and the through hole. The groove is exposed to the outside and defined around the center line of the dielectric substance. The through hole is defined to have a given length shorter than the preselected length of the dielectric substance for achieving a small-sized structure with a high unloaded Q which may be manufactured in a simple manner.
