摘要：
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.
