Dielectric resonator dual modes filter
Abstract
It is noted that in a shielded cylindrical dielectric resonator a number of degenerate modes with identical natural frequencies can be found. Further, these degenerate modes can be coupled together to form coupled circuits by perturbating the geometrical configuration of the structure. Attention is given to both TE(01p) mode resonant frequency perturbation by a tuning screw and a two modes dielectric filter using two perpendicularly polarized HE(111) modes of the resonator
