Problems solved by technology

However, base station antennas are faced with a variety of working environments, and the polarization modes of the interference source signals are different. The above-mentioned base station antennas cannot adjust the angle of the radiation unit, so the polarization mode cannot be adjusted, and the interference sources cannot be adapted to changeable sources. Unable to achieve the purpose of anti-interference

Abstract

The embodiment of the invention discloses a base station antenna with the adjustable polarization, and is used for enabling a radiation unit to freely rotate. The base station antenna with the adjustable polarization, which is provided by the embodiment of the invention comprises a reflection plate, radiation units, rotation pieces and transmission devices, wherein the reflection plate is provided with a plurality of radiation units; the radiation units are fixedly arranged on the rotation pieces and can freely rotate along with the rotation pieces; and the transmission device is used for driving the rotation pieces to rotate. According to the base station antenna with the adjustable polarization, which is disclosed by the invention, the radiation units are fixedly arranged on the rotation pieces and can freely rotate along with the rotation pieces, and therefore the polarization mode is changed and can adapt to various interference sources to achieve a purpose of resisting interference.

Description

technical field [0001] The present invention relates to the field of machinery, and in particular to a polarization-adjustable base station antenna. Background technique [0002] In the communication system, the antenna is the converter of the circuit signal of the communication equipment and the space radiation electromagnetic wave, and is the bridgehead of the space wireless communication. Therefore, the base station antenna is an important part of the mobile communication system, and its characteristics directly affect the overall performance of the entire wireless network. In the engineering design of mobile communication network, base station antennas should be reasonably selected according to actual conditions such as network coverage requirements, traffic distribution, anti-interference requirements and network service quality. [0003] As a base station antenna, the general polarization mode is fixed. For example, the most widely used positive and negative 45° orthog...
