Abstract

The invention discloses an ultra-wideband antenna and an ultra-wideband communication device. The ultra-wideband antenna comprises a dielectric substrate, a coaxial feeder line, two radiation patchesand a plurality of lumped resistors, wherein a through hole is formed in the geometric center of the dielectric substrate; the two radiation patches are in central symmetry with the through hole as the symmetry center, no electrical connection exists between the two radiation patches, and the radiation patches are provided with notches inwards from the edge. The lumped resistors is are loaded at the tail end of the radiation patches; and the coaxial feeder line is electrically connected with the two radiation patches through the through holes respectively. The ultra-wideband antenna provided by the invention adopts a bow-tie-shaped structure and has a stable phase center, and; in addition, the lumped resistors is are loaded at the tail end of the radiation patches with the notch, es so that the ringing phenomenon at the tail end of a the time domain signal can be effectively inhibited, the time domain performance of the antenna can be further improved, and the ultra-wideband antenna also conforms to the antenna design trend of compact and miniaturized structure.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ultra-wideband antenna and an ultra-wideband communication device. Background technique [0002] Antenna is a key component in a wireless communication system, radiating electromagnetic waves and receiving electromagnetic waves is the key role played by an antenna in a wireless communication system. In recent years, with the increase of wireless communication demand and the continuous improvement of communication rate, ultra-wideband communication has gradually shown its advantages, which makes the corresponding antenna design must meet its bandwidth requirements, and ultra-wideband communication technology One of the key components of the UWB antenna is the ultra-wideband antenna, which makes the UWB technology of the antenna also receive attention and development. [0003] At present, UWB antennas are widely used in systems such as ground penetrating radar, t...
