Summary: | PROBLEM TO BE SOLVED: To provide a dielectric resonator and its frequency setting method where the setting of the frequency is changed without changing an internal structure and its shape and without much reducing the impedance. SOLUTION: A center conductor 1 is built in a dielectric body 2 by a lamination structure and a laminator is formed by sintering it. A hot terminal electrode 5 is formed to one end of the laminator and a ground terminal electrode 6 is formed to the other end. Both ends of the center conductor 1 connect to the hot terminal electrode and the ground terminal electrode 6. The center conductor 1 opposes to the ground electrodes 3, 4 provided on the laminator via the dielectric layer. A dielectric constant of a material 2a toward the hot terminal electrode 5 of the dielectric body 2 is selected to be relatively higher than that of a material 2b toward the ground terminal electrode 6. The resonance frequency is set by changing a ratio of the width of the high dielectric constant material 2a to that of the low dielectric constant material 2b in the lengthwise direction of the center conductor. |
