Title:
MULTIPLE MODE DIELECTRIC RESONATOR AND ITS CHARACTERISTIC ADJUSTMENT METHOD
Document Type and Number:
Japanese Patent JP3298485
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the multiple mode dielectric resonator where each resonance frequency in three resonance modes is decided or the multiple mode dielectric resonator where a degree of coupling among prescribed resonance modes is decided by using a composite dielectric pillars consisting of pluralities of crossed dielectric pillars so as to produce the three resonance modes depending on a plane formed by the two dielectric pillars.
SOLUTION: Two TM110 modes, where the axis of symmetry of electric field distribution differs, are used as 1st and 3rd resonance modes, the TM111 mode is used as a 2nd resonance mode. Then the resonance frequency of the 1st resonance mode is selectively decided by providing dielectric bode elimination parts like 5a, 5b to spaces where the electric field distribution in the 1st resonance mode is concentrated and the electric field distribution in the 2nd and 3rd resonance modes is not concentrated.
