Claim 14:
15. 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 resonant rod further comprises a coupling segment connected between the first branch and the extension segment, and a width of the coupling segment is less than that of the first branch connected to the coupling segment.
