Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and in particular, to an ultra-wideband antenna and equipment. Background technique [0002] In recent years, ultra-wideband technology has gradually begun to be applied, which also puts forward higher requirements for antenna technology. The standing wave of the traditional loop antenna is poor in some frequency bands, so it is difficult to widen the working frequency band. Contents of the invention [0003] The main purpose of the embodiments of the present invention is to provide an ultra-wideband antenna and equipment, aiming at solving the problem of the loop antenna having a standing wave difference in some frequency bands and making it difficult to widen the operating frequency band. [0004] To achieve the above purpose, an embodiment of the present invention provides an ultra-wideband antenna, the ultra-wideband antenna includes: [0005] a dielectric subst...
