Abstract
In one embodiment, a polarization control system for an antenna array comprises a number of first and second antenna elements and a beam forming network. The first antenna elements have a direction of polarization that is different from a direction of polarization of the second antenna elements. The beam forming network, which is coupled to the first and second antenna elements, is operable to provide a second signal to a first subset of the plurality of first antenna elements that is different from a first signal that is provided to the other first antenna elements and provide a third signal to a second subset of the second antenna elements that is different from the first signal that is provided to the other second antenna elements.
