description The invention provides an ultra-bandwidth UWB dual-band antenna with low cross polarization suppression. The ultra-bandwidth UWB dual-band antenna comprises an LCP stacking layer and an antenna layer, the antenna layer is arranged above the LCP stacking layer; the antenna layer comprises a plurality of antenna units; and the feeding point position and the transmission line length of each antenna unit are consistent, so that the transmission line impedance of each antenna unit is the same. According to the UWB antenna, the design of equal-length transmission lines excited at the same position is adopted on the basis of the LCP stacking technology, the low cross polarization suppression performance can be improved under the condition that the high requirements for the amplitude, the phase and the directional diagram of the UWB positioning antenna are met, meanwhile, the antenna bandwidth is remarkably improved, and the signal transmission power and the positioning accuracy are improved; and the device can be in
