Claim Text:
1. An ultra-wideband antenna, comprising: a coplanar waveguide feeder, a tapering supporting arm, a primary radiating closed-band-shaped monopole, a primary coupling patch, a secondary radiating closed-band-shaped monopole, a secondary coupling patch and a Printed Circuit Board (PCB) substrate, wherein the coplanar waveguide feeder, the tapering supporting arm, the primary radiating closed-band-shaped monopole and the primary coupling patch are located on one side of the PCB substrate, and the secondary radiating closed-band-shaped monopole and the secondary coupling patch are located on the other side of the PCB substrate; the coplanar waveguide feeder is connected to a Radio Frequency (RF) excitation port on the PCB substrate at one end, and connected to the tapering supporting arm at the other end, and is configured to transmit a current of the RF excitation port to the tapering supporting arm; the tapering supporting arm is connected to the coplanar waveguide feeder at one end, and connected to the primary radiating closed-band-shaped monopole at the other end, and is configured to transmit the current to the primary radiating closed-band-shaped monopole; the primary radiating closed-band-shaped monopole is connected to the tapering supporting arm, and forms electromagnetic coupling with the primary coupling patch; the primary coupling patch is located in the area closed by the closed band of the primary radiating closed-band-shaped monopole, and is spaced apart from the primary radiating closed-band-shaped monopole by a distance that enables the primary radiating closed-band-shaped monopole to form electromagnetic coupling with the primary coupling patch; the secondary radiating closed-band-shaped monopole is connected to the primary radiating closed-band-shaped monopole through a metallic via, and forms electromagnetic coupling with the secondary coupling patch; and the secondary coupling patch is located in the area closed by the closed band of the secondary radiating closed-band-shaped monopole, and is spaced apart from the secondary radiating closed-band-shaped monopole by a distance that enables the secondary radiating closed-band-shaped monopole to form electromagnetic coupling with the secondary coupling patch.
