Abstract

The embodiment of the invention provides a multi-feed antenna and communication equipment, relates to the technical field of communication, and aims to realize ultra-wideband frequency tuning. The antenna comprises a first antenna radiator, and a plurality of feed points corresponding to the first antenna radiator, wherein the multiple feed points are used for inputting transmission signals to thefirst antenna radiator. According to the invention, the multi-feed antenna does not contain a matching network; ultra-wideband frequency tuning can be realized by adjusting the parameters of the transmission signals input to each feed point in the multiple feed points, so that loss and complex matching circuit design are avoided; the multiple feeding points correspond to one first antenna radiator, so that the antenna radiator is simpler in design, and coupling between the radiators does not need to be considered; and due to the fact that the multi-feed antenna can achieve ultra-wideband frequency tuning, the multi-feed antenna has more response frequency bands and has good low-frequency response.
