Ultra-wideband antenna and electronic equipment

The invention provides an ultra-wideband antenna and electronic equipment, and relates to the technical field of mobile communication, and the ultra-wideband antenna comprises a first substrate; the feed structure is arranged on one side of the first substrate; the radiation structure is arranged on one side of the first substrate and is electrically connected with the feed structure; the radiation structure comprises a radiation patch and a notch unit, and the radiation patch is electrically connected with the feed structure. The novel ultra-wideband antenna with the reconfigurable trapped wave characteristic provided by the invention can have the characteristic of relatively wide broadband, and can also trap waves, so that mutual interference with communication protocols of other frequency bands in the use process is reduced or even avoided.
