A 4×4 antenna system for MIMO applications will be described along with performance data. This antenna system provides coverage for all 4G frequency bands in the 1700 to 4000 MHz range. To complement this presentation a description of an antenna optimization technique will be provided were a 5 GHz active steering antenna module is described for use in TV set-top boxes and access points for HD video streaming in home (802.11a, n, ac applications). Multiple active steering antennas can be used to form a 3×3 or 4×4 MIMO system where each antenna has optimized radiation patterns based on the dynamic mode selection process we implement. This active steering technology can be implemented at both cellular and WLAN bands.
