1. A wireless network device, comprising:
an antenna array, comprising a plurality of antenna elements, each having a vertical polarized signal and a horizontal polarized signal;
a wireless network interface, wherein the wireless network interface receives an incoming signal from one of the antenna elements in the antenna array;
a processing unit; and
a switching network disposed in an electrical path between the antenna array and the wireless network interface to select an antenna element from the antenna array, wherein the switching network comprises one or more selection switches that act as multiplexers and demultiplexers, depending on a direction of activity, the one or more selection switches in communication with the vertical polarized signal and the horizontal polarized signal from each of the plurality of antenna elements and configured to couple the horizontal polarized signal or the vertical polarized signal from any of the plurality of antenna elements to the wireless network interface and is also configured to couple at least one circular polarized signal to the wireless network interface, wherein each circular polarized signal is created by combining the vertical polarized signal and the horizontal polarized signal from a single antenna element.
