    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.

    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.
