Problems solved by technology

[0003] At present, the broadband antenna system used by the base station site includes high-frequency antenna units and low-frequency antenna units. When adjusting the downtilt angle, the high-frequency and low-frequency antenna units need to be adjusted separately. Therefore, the cost is relatively high, and the adjustment of the downtilt angle is more complicated.

Abstract

The embodiment of the invention provides a broad-band antenna system, a base station and a method for adjusting the declination angle of a broad-band antenna, relates to the technical field of communication and aims at effectively reducing the cost. The broad-band antenna system comprises a first antenna unit and a second antenna unit, wherein a phase shift unit is connected between the first antenna unit and the second antenna unit, the phase shift unit connected between the first antenna unit and the second antenna unit is controlled by an electric tuning motor, under the rotation of the electric tuning motor, the phase shift unit connected between the first antenna unit and the second antenna unit is used for simultaneously adjusting the declination angle of the first antenna unit and the declination angle of the second antenna unit. The invention can be used in a wireless communication system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a broadband antenna system, a base station and a method for adjusting the downtilt angle of the broadband antenna system. Background technique [0002] In a mobile communication system, the downtilt angle of the base station antenna determines the coverage area of ​​the antenna beam. In order to optimize the coverage of the wireless signal of the cellular cell and to suppress the same-frequency interference between the same-frequency cells, it is necessary to reasonably adjust the downtilt angle of the base station antenna. Moreover, since the spatial attenuation of signals of different frequencies is different, and the spatial attenuation of high-frequency signals is large, to achieve the effect of multi-frequency coverage, antennas in high and low frequency bands are required to have different downtilt angles. [0003] At present, the broadband antenna system used by th...
