    Abstract: An exemplary alignment module for a base station antenna has one or more accelerometers and one or more magnetometers. The one or more accelerometers are used to determine tilt and roll angles of the antenna, while the yaw angle of the antenna is determined using the one or more magnetometers and the determined tilt and roll angles. Using multiple accelerometers and/or multiple magnetometers can improve accuracy of angle determination. A service provider can determine when to re-align the antenna by monitoring the tilt, roll, and yaw angles remotely to detect changes in antenna orientation. Yaw angle determination can also take into account offset values corresponding to soft-iron effects, hard-iron effects, and factory calibration. The need to re-calibrate offset values following changes in local magnetic environment can be detected by comparing different sensor signals, such as the different magnetic fields detected by a plurality of magnetometers.

    Abstract translation: 用于基站天线的示例性对准模块具有一个或多个加速度计和一个或多个磁力计。 使用一个或多个加速度计来确定天线的倾斜角和倾斜角，同时使用一个或多个磁力计确定天线的偏转角和确定的倾斜和滚动角。 使用多个加速度计和/或多个磁力计可以提高角度确定的精度。 服务提供商可以通过远程监控倾斜，滚动和偏航角来确定何时重新对准天线，以检测天线方向的变化。 偏角确定也可以考虑对应于软铁效应，硬铁效应和工厂校准的偏移值。 可以通过比较不同的传感器信号（例如由多个磁力计检测到的不同的磁场）来检测在局部磁环境变化之后重新校准偏移值的需要。

    Abstract: A base station antenna system includes a plurality of sector antennas angularly spaced around a support structure at approximately equal azimuth angles. A feed network is coupled to the plurality of sector antennas and provides a common RF signal to the plurality of sector antennas and applies at least one phase difference to at least one sector antenna of the plurality of sector antennas. In one example, the base station antenna system includes first, second and third sector antennas angularly spaced at 120° intervals and the feed network applies a 120° phase difference to the second sector antenna and a 240° phase difference the third sector antenna. In another example, the base station antenna system includes first, second, third and fourth sector antennas angularly spaced at 90° intervals and the feed network applies a 180° phase difference to the second and fourth sector antennas.
