Patent ID: 7308749

Claim:
A method of producing a dielectric resonator, the method comprising: moving a rotary cutting disk in a depth direction of at least one hole in a dielectric block, the rotary cutting disk having an axis of rotation substantially perpendicular to the depth direction of the at least one hole; abutting an edge of an opening of the at least one hole with the rotary cutting disk; and cutting an inner conductor within the at least one hole together with an outer conductor on an outer surface of the dielectric block such that the inner conductor and the outer conductor are separated from each other only at the edge of the opening of the at least one hole so that the at least one hole is formed into a resonator having a stray capacitor at the opening of the at least one hole, wherein the dielectric block includes a plurality of holes, each of the plurality of holes having a depth direction, and the cutting of the inner conductor and the outer conductor of each of the plurality of holes is carried out by a respective plurality of cutting disks, each cutting disk of the plurality of cutting disks rotating about an axis perpendicular to the depth direction of the hole corresponding to that cutting disk.
