Abstract
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.
