ABSTRACT:
A dielectric resonator apparatus includes at least one dielectric coaxial resonator in a dielectric block of a dielectric material having first and second end surfaces, and a plurality of side surfaces. At least one cylindrical resonator hole is disposed so as to penetrate the dielectric block and an outer conductor is disposed on at least the first end surface and, the plurality of side surfaces. Further, at least one inner conductor is disposed in the resonator hole so that one end thereof located on the first end surface side is electrically insulated from the outer conductor, thereby constituting at least one dielectric coaxial resonator. A pair of input and output electrodes is disposed on at least one predetermined side surface of the dielectric block so as to be electrically insulated from the outer conductor and to be close to one end of the inner conductor located adjacent the first end surface. Furthermore, two penetrating holes are disposed so as to penetrate the dielectric block between a pair of input and output electrodes and the inner conductor, and two connection conductors for electrically connecting a pair of input and output electrodes to the inner conductor are disposed in the penetrating holes.
