Compactly coupled dual-mode dielectric resonance filter

The invention relates to a compactly coupled dual-mode dielectric resonance filter, and belongs to the technical field of communication. The compactly coupled dual-mode dielectric resonance filter comprises a metal housing, two or more than two dielectric resonators arranged in the cavity of the metal housing, supports the number of which corresponds to that of the dielectric resonators and a pair of input/output devices used for introducing electromagnetic energy into the metal housing and extracting electromagnetic energy from the metal housing. Each dielectric resonator is mounted on the upper end of one support in the height direction, the supports are vertically fixed on a bottom wall of the cavity of the metal housing, the input/output devices are installed on an inner side wall of the metal housing and are respectively located on one end and the other end of the cavity of the metal housing in the length direction, the lower end of each support in the height direction extends out of the metal housing an
