According to the miniaturized metal plate combiner, the front end and the rear end of each resonance piece are bent upwards to form the bent structures used for coupling of the adjacent resonance pieces, coupling is enhanced by adjusting the distance and the relative area between the bent structures of the adjacent resonance pieces, coupling bandwidth adjustment is achieved, and under the condition that the size is limited, the coupling bandwidth can be adjusted, and the miniaturization of the metal plate combiner is achieved. Compared with a common coaxial metal scheme, the bending structure has the advantages that the height and the size are obviously reduced; meanwhile, a tuning channel penetrating through the end face of the cover plate is formed in the area, located above the bent structures of any two adjacent resonance pieces, of the cover plate, the distance and the relative area of the bent structures are changed in the mode that the pieces are shifted through the tuning channels in the cover plate,
