Abstract
Antenna systems are provided. In one example, an antenna system includes a first antenna array having a plurality of first antenna elements. The first antenna elements are operable to communicate one or more signals via a communication protocol tin a multiple input multiple output (MIMO) mode. The antenna system includes a second antenna array having a plurality of second antenna elements. The antenna system includes a control circuit configured to control operation of one or more of the second antenna elements of the second antenna array in a first mode or a second mode. In the first mode, one or more of the second antenna elements are configured to provide a secondary function to support communication of the first antenna elements via the communication protocol. In a second mode. One or more of the second antenna elements are configured to support beam forming or beam steering of the first antenna elements.
