Dielectric resonator and method for adjusting resonance frequency of dielectric resonator

Abstract

Abstract PURPOSE:To adjust easily and accurately a resonance frequency by providing an electrode for capacitance adjustment formed with many metallic pieces in mesh form to an open end side of a dielectric resonator so as to control the area of the electrode. CONSTITUTION:The electrode 35 for capacitance adjustment made of many metallic pieces divided minutely is provided to an upper face (open end side) 34 of the dielectric resonator 31 consisting of one dielectric and the electrode 35 is connected to a metallic rod (inner conductor) 36. In cutting the resonator into halves and viewing them from the X direction, a dielectric 53 is found between the electrode 52 and a side face 54, and when the electrode 52 and the side face 54 are approached together, the capacitance 55 formed by them is increased and the resonance frequency of the resonator is decreased. Thus, when B (1, 1) and B (1, n) are cut off from the metallic pieces divided minutely of the electrode, it is found that the resonance frequency is increased most. The resonance frequency is adjusted easily and accurately by controlling the area of the electrode in this way.
