Abstract: The present application provides an ultra-wideband antenna and an electronic apparatus, which relates to the technical field of mobile communication. The ultra-wideband antenna includes: a first substrate; a feed structure provided at a side of the first substrate; and a radiating structure provided on the one side of the first substrate and electrically connected to the feed structure, wherein the radiating structure includes a radiating patch and a wave-trapping unit, and the radiating patch is electrically connected to the feed structure. The novel ultra-wideband antenna has the characteristic of being capable of reconstructing the trapped wave provided by the present application may have a wide broadband, and may also trap wave, thereby reducing or even preventing mutual interference with communication protocols of other frequency bands during use.
