摘要： A dielectric filter is made of a dielectric material and includes a molded member of a pillar shape which has a hole formed from the top surface thereof toward the inside, an inner electrode formed so as to cover the inner circumferential surface of the hole; an outer electrode provided so as to cover the outer surface of the molded member except a prescribed region, and a coupling electrode provided at least in a portion of the prescribed region. An electrode area of a region of the inner electrode which faces against the coupling electrode is adjusted, thereby adjusting the coupling capacitance which is formed between the inner electrode and the coupling electrode.

摘要： This invention relates to a compact and high performance microwave stripline resonator consisting of a dielectric substrate provided with a strip electrode and a depression coated with an electrode which is connected to an end of the strip electrode provided on one of the surfaces of the dielectric substrate and a grounding electrode provided on the other surface of the dielectric substrate, and the grounding electrode is connected to the other end of said strip electrode. With this dielectric resonator construction, the characteristic impedance of the strip electrode and the characteristic impedance of the electrode coated on the depression are made different. As a result of this, the length of microwave stripline can be shortened without sacrificing the Q of the resonator. This is highly effective to realize compact resonators.

摘要： A dielectric resonator includes a resonator body having a groove formed in its upper surface adjacent to an outer periphery of a through hole formed through the body. An electrically-conductive film on the inner surface of the groove is electrically connected to an electrically-conductive film formed on the inner peripheral surface of the through hole, via an electrically-conductive film formed on a portion of the upper surface of the body lying between the groove and the through hole. The groove having the electrically-conductive film formed on its inner surface enables the length of the body to be reduced and the overall resonator to have a reduced size.
