The multiplex mode dielectric resonator device, the dielectric core is laid out inside the dielectric filter,

摘要

Two TE modes where the surface where electric field turns is a relationship of crossing, becoming independent with the connection between two TM modes where electric field faces to the direction which is relationship of that same crossing respectively it makes connect. The dielectric core (1) the higher stratum of society section (La) with the lower stratum (Lc) the swelling section (Pe1) and (Pe2) providing in the multiplex mode dielectric resonator device which four modes of TM01-x mode, TM01-y mode, TE01-x mode and TE01-y mode occur, it can give difference in effective permittivity of respective part which the electric flux of occasional mode and odd mode of TE coupled modes passes. In addition in order effective permittivity of the part which the dielectric core (1) the electric flux of occasional mode and odd mode of TM coupled modes passes to intercellular layer section Lb to become abbreviation equal, the swelling section (Pc) it forms. Because of this while controlling the connection of TM01-x mode -TM01-y mode, it assures the connection of TE01-x mode -TE01-y mode.
