ABSTRACT:
A dielectric resonator apparatus comprising a plurality of dielectric coaxial resonators has a dielectric block with first and second surfaces and a plurality of side surfaces located therebetween, and a plurality of cylindrical resonator holes are formed in parallel to each other so as to penetrate the dielectric block, each of the resonator holes having an opening at the first surface and another opening at the second surface. Further, an outer conductor is formed on the first and second surfaces and a plurality of side surfaces, and a plurality of inner conductors is formed on the plurality of resonator holes, respectively. Then a plurality of extending conductors is formed in the vicinity of the openings of the plurality of resonator holes, respectively, so as to extend from the outer conductor to the plurality of resonator holes and to form gaps between the plurality of extending conductors and the inner conductors, each of the inner conductors having open-circuit ends in the vicinity of both the openings of the resonator holes, thereby constituting a plurality of dielectric coaxial resonators. Furthermore, a pair of input and output electrodes is formed on the side surfaces so as to be electrically insulated from the outer conductor.
