Zusammenfassung:An antenna system for a wireless device and a method for operating same are provided for controlling radiation characteristics of the antenna system. The antenna system includes first and second sets of feed points disposed so that first and second radiation pattern are generated by the antenna system when drive currents are provided at the first and second set of feed points, respectively. The second radiation pattern is different from the first radiation pattern. The first and second drive currents are supplied such that a predetermined overall radiation pattern is generated. The predetermined overall radiation pattern is at least in part a combination of the first radiation pattern and the second radiation pattern. The system and method may be directed toward SAR mitigation.
