First Claim
1. An antenna system including a plurality of antennas, the antenna system comprising:
- a first antenna;
a second antenna;
a measurement device, the measurement device 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;
an antenna selection controller configured to select one of the first antenna and the second antenna 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;
a coupler; and
first and second switches,wherein the coupler has a first signal connection and a second signal connection and a first signal measurement connection and a second signal measurement connection, the first signal connection coupled to the first switch, the second signal connection coupled to a power amplifier, the first signal measurement connection and the second signal measurement connection alternatively coupled to ground and a transceiver based on a state of the second switch.

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.
