description The invention discloses a dual-frequency broadband omnidirectional antenna based on multimode resonance. The dual-frequency broadband omnidirectional antenna comprises a radiation structure, a feed structure and a feed connector, the radiation structure comprises an upper micro-strip layer, a radiation structure dielectric plate, a metal column and a lower micro-strip layer which are arranged in sequence; the upper microstrip layer comprises two symmetrical radiation branches, and the feed connection part is arranged between the two radiation branches; one end of the feed structure is vertically inserted into the radiation structure and is connected with the radiation structure through the bonding pad, and the other end of the feed structure is connected with the feed connector. The symmetrical radiation branches excite the first odd-order dipole mode and the second odd-order dipole mode, good omnidirectional radiation of a low-frequency band is guaranteed, and resonance of a high-frequency band is generated.
