Abstract
An antenna system includes a plurality of antenna feed points operatively coupled to one or more antennas and a controller for selecting at least one of the antenna feed points based on the operating environment of the antenna system. When the antenna system is employed in a mobile wireless device, selecting a particular antenna feed point can modify the device'"'"'s surface current distribution to improve the antenna system'"'"'s performance over the effects of near field conditions.
