Abstract:
A dielectric electronic component for a communication device comprising:a plurality of resonators provided in a dielectric ceramic block, each of which includes a through hole bored through the dielectric ceramic block and having an inner peripheral surface coated with an internal conductor; a plurality of excitation holes formed in the dielectric ceramic block and electromagnetically coupled with the resonators, each of which has an inner peripheral surface coated with an internal conductor, said resonators and said excitation holes being arranged in parallel with each other; the dielectric ceramic block having a top surface on which open-circuiting ends of the resonators and short-circuiting ends of the excitation holes are defined; the dielectric ceramic block having a bottom surface on which short-circuiting ends of the resonators and the open-circuiting ends of the excitation holes are defined; the dielectric ceramic block having an outer peripheral surface coated with an external conductor except regions surrounding the open-circuiting ends of the resonators and those of the excitation holes; and the short-circuiting ends of the excitation holes being provided with respective coupling-adjusting countersinks each having an increased diameter.
