Claim 15:
16. A resonant filter, comprising:
a housing including an input hole, an output hole, and an accommodating cavity provided in the housing;
an input resonator located in the accommodating cavity and fixed in the housing, and including an input resonant body and an input port extending from the input resonant body and extending out of the housing through the input hole; and
an output resonator located in the accommodating cavity and fixed in the housing, and including an output resonant body and an output port extending from the output resonant body and extending out of the housing through the output hole;
wherein the input resonator and the output resonator are sheets with a metal surface or metal sheets, the input resonator body and the output resonator body respectively include a resonant rod, and the resonant rod includes an upright segment, an extension segment extending from one or both sides of the upright segment, and a first branch extending from the extension segment away from the upright segment, and an end of the upright segment away from the extension segment is connected to the housing;
wherein the number of the first branches is plural, and the first branches are spaced apart from each other and connected to the extension segment;
wherein the resonant rod further comprises a plurality of second branches, the second branches respectively extend from ends of the first branches away from the extension segment, and the first branches and the second branches extend along different axial directions.
