Abstract: A systems, methods and apparatus including a plurality of antennas are provided. The antenna system includes a first antenna, a second antenna, and a measurement device. The measurement device is configured to measure at least a first complex value indicative of an impedance matching of the first antenna and a second complex value indicative of an impedance matching of the second antenna. The antenna system includes an antenna selection controller configured to select one of the first antenna and the second antenna. The antenna selection controller making the selection based on the measurement of the first complex value of the first antenna and the measurement of the second complex value of the second antenna.
