Abstract
An antenna system connected to a radio in a Multiple-Input, Multiple-Output (MIMO) arrangement and configured to communicate in an area of coverage. The antenna system includes a plurality of antenna elements. The plurality of antenna elements further includes a first plurality of antenna elements configured to communicate on a first frequency band and a second plurality of antenna elements configured to communicate on a second frequency band. A plurality of MIMO-configured radio ports on the radio communicates radio signals to and from the antenna elements. A beam-forming network is connected to at least two of the first plurality of antenna elements and to at least two radio ports. The beam-forming network is configured to form space diversity beams in the area of coverage.
