Title:
BASE STATION, ANTENNA, AND RADIATION UNIT THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/142486
Kind Code:
A1
Abstract:
The present disclosure provides a base station, an antenna, and a radiation unit thereof. The radiation unit comprises two pairs of radiation oscillators in polarized orthogonal arrangement, and the two radiation oscillators having the same polarization are opposite to each other to form a matrix structure. The radiation unit is characterized in that: the radiation surfaces of the radiation unit is restricted to the same plane, while the non-radiation surface thereof is provided with a cutting structure so as to be separated from the restriction of the same plane; and the cutting structure causes radiation oscillators on two sides of a first vertical midline of the matrix structure to form a symmetrical structure with respect to the first vertical midline, and causes radiation oscillators on two sides of a second vertical midline of the matrix structure to form an asymmetrical structure with respect to the second vertical midline. In the radiation unit of the present disclosure, a cutting structure is provided on two radiation vibrators on one side of the second vertical midline such that the radiation unit is asymmetric with respect to the second vertical midline, thereby widening the frequency band of the radiation unit and improving the horizontal symmetry of the downward tilt radiation pattern.
