Ultra-wideband antenna and terminal

Abstract

The present disclosure discloses an ultra-wideband antenna, including: a coplanar waveguide feeder connected to a Radio Frequency (RF) excitation port on the PCB substrate at one end and to a tapering supporting arm at the other end; the tapering supporting arm connected to the coplanar waveguide feeder at one end and to a primary radiating closed-band-shaped monopole at the other end; the primary radiating closed-band-shaped monopole connected to the tapering supporting arm; a primary coupling patch located in the area closed by the closed band of the primary radiating closed-band-shaped monopole; a secondary radiating closed-band-shaped monopole connected to the primary radiating closed-band-shaped monopole through a metallic via; and a secondary coupling patch located in the area closed by the closed band of the secondary radiating closed-band-shaped monopole. The present disclosure also discloses an ultra-wideband terminal. With the antenna and the terminal of the present disclosure, space usage is reduced, facilitating development of an ultrathin terminal and widening bandwidth, and thus allowing the terminal to operate in the range of an ultrawide band.
