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.
