1. An ultra wide band antenna structure, comprising:
a dielectric substrate;
an antenna structure, located on a side of the dielectric substrate, wherein the antenna structure comprises a radiation patch and a feeder line; and
a ground layer, located on a side of the dielectric substrate facing away from the antenna structure;
wherein the radiation patch has a first hollowed-out slit, in a same antenna structure, the first hollowed-out slit is located in a side of the radiation patch away from the feeder line; and a length of the first hollowed-out slit is related to λ/2; and λ represents a wave length in a frequency band of a needed notch wave;
the first hollowed-out slit comprises a first slit part, a second slit part and a third slit part; wherein the first slit part extends in a first direction, the second slit part and the third slit part respectively extend in a second direction, and the first direction intersects with the second direction; the second slit part is connected with a first end of the first slit part, the third slit part is connected with a second end of the first slit part, and the first slit part extends from the first end of the first slit part to the second end of the first slit part.
