A dielectric resonator ( ) having three surfaces formed by chamfering three ridged portions sharing an apex of a dielectric block and another three surfaces adjacent respectively thereto, in which each of the chamfered surfaces and the adjacent surfaces thereto offers an angle of 45 degrees and an area ratio of the chamfered surfaces with respect to the adjacent surfaces is 45% is mounted in a cut-off waveguide of a generally rectangular parallelopiped ( ) and feeding probe ( ) and ( ) are provided for composing a dielectric filter.

Dielectric resonator and dielectric filter

In order to provide a dielectric resonator filter which can be reduced in dimension, can be reduced in height, and can be surface-mounted, in a dielectric resonator filter including a rectangular-parallelopiped or polygonal-pole-like metal cavity in which at least one dielectric resonator is arranged between one pair of input/output probes, the input/output probes are attached to corner portions of the rectangular-parallelopiped metal cavity.
