Aspects of the present disclosure may be directed to a reconfigurable antenna system including a reconfigurable antenna capable of providing various types of radiation patterns without having to be replaced or needing its orientation changed. The reconfigurable antenna may create various types of quasi-omni directional radiation patterns of different shapes depending on the environment.

Circular base station antenna array and method of reconfiguring the radiation pattern

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&#xb0; intervals and the feed network applies a 120&#xb0; phase difference to the second sector antenna and a 240&#xb0; 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&#xb0; intervals and the feed network applies a 180&#xb0; phase difference to the second and fourth sector antennas.
