The method of producing the microwave resonator and that kind of resonator and the method of compensating the temperature coefficient of resonance frequency of the microwave resonator

摘要

(57) Abstract It regards the microwave resonator which has with the expedient where, this invention takes in and/or extending into the resonator space and this resonator space, removes microwave. As for topic of this invention, there are times when the microwave resonator which can decrease the temperature dependancy of resonance frequency of the microwave resonator is offered. Because of this, temperature coefficient provides the negative dielectric inside the resonator space. In order to form at least the portion of the wall of the resonator space which works as an electric seal when superconductivity and the especially hot superconducting material are used, it is profitable.
