摘要
A coaxial resonator comprising an outer conductor with closed and open ends, an inner conductor concentrically disposed in the outer conductor to establish a short circuit at the closed end and an open circuit at the open end, and a dielectric member mounted in the open circuit between the outer and inner conductors. An electrode is connected to the open circuit end of the inner conductor with a spacing from the dielectric member. A conductive plate, having a smaller surface area than that of the electrode but larger than the transverse cross-sectional area of the inner conductor, is provided between the dielectric member and the electrode. The dimensions of the conductive plate is appropriately chosen to accommodate frequency variations which might occur as a result of a connection with an external circuit.
