Problems solved by technology

[0003] During network optimization, the preset pitch angles of antennas in the two installation methods generally do not meet the coverage requirements, and professionals need to adjust the pitch angles during train non-operating hours, resulting in time-consuming and laborious network optimization.

Abstract

The invention discloses a tunable antenna of a base station. The tunable antenna comprises an antenna with a plurality of antenna arrays, a plurality of phase shifters, a remote control unit and a transmission mechanism; the plurality of phase shifters are respectively and correspondingly connected with the antenna arrays and are used for adjusting the phases of the radio frequency signals passingthrough the antenna arrays so as to change the pitch angles of the antenna beams; and the remote control unit and the transmission mechanism control the plurality of phase shifters, so that the phases of the radio frequency signals received or to be transmitted by the antenna arrays in the target direction of the wave beam are the same. According to the technical scheme of the invention, the pitch angle of the antenna beam can be remotely controlled and adjusted, so the wireless signal coverage of the cell is optimal, and the same-frequency and different-frequency interference of adjacent cells is minimized.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an electronically adjustable antenna for a base station. Background technique [0002] In order to cover the traffic network such as railways and expressways, the ultra-high-speed wireless communication network must set up wireless communication base stations along the road network. Taking railways as an example, iron towers or catenary poles along railway lines are often used to install base station antennas. Usually the base station antenna is installed on the iron tower much higher than the terminal antenna, and the electric adjustable antenna only needs to support antenna downtilt adjustment, while the wireless base station antenna will not only be installed on the communication iron tower, but also on the catenary pole. The height difference between the base station antenna on the catenary pole and the train roof is less than 2 meters. When the tr...
