A transverse magnetic mode dielectric resonator, comprising:
- a resonant cavity with inner surfaces including an inner bottom surface, and with an opening at one end of the resonant cavity, and a dielectric resonant column positioned in the resonant cavity, wherein a bottom end surface of the dielectric resonant column contacts the inner bottom surface of the resonant cavity, and the inner surfaces of the resonant cavity are covered with conductive material, the transverse magnetic mode dielectric resonator further comprising:
- a thin cover board covering the opening and a thick cover board covering the thin cover board, wherein surfaces of the thin cover board and the thick cover board are covered with conductive material;
- and
- a slot arranged on a surface of the thick cover board where the thick cover board contacts the thin cover board, wherein the slot is filled with filler, and the filler is a compressible material that causes the thin cover board to experience elastic deformation when the thick cover board with the filler covers the thin cover board, wherein the filler fills in the slot arranged on the thick cover board.
A base station, comprising a transverse magnetic mode dielectric filter which includes a transverse magnetic mode dielectric resonator, wherein the transverse magnetic mode dielectric resonator comprises:
