Abstract
Abstract A dielectric resonator is made up of a block of dielectric material and a synthetic resin bonded onto the dielectric material for precisely adjusting the required resonance frequency of the resonator. The resonance frequency is reduced by an increase of the amount of synthetic resin and the resonance frequency is increased by a decrease of the mass of synthetic resin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A dielectric resonator structure for use in a resonator, which comprises: a block of dielectric material; a support of dielectric material a bonding material bonding said block to said support; and, in addition to said bonding material, a mass of synthetic resin essentially of dielectric material bonded onto said block of dielectric material for precisely adjusting the resonance frequency of the block of dielectric material, whereby the resonance frequency can be decreased by an increase of the mass of synthetic resin and the resonance frequency can be increased by an decrease of the mass of synthetic resin.
Claim 2
Dependent Claim
