Abstract
The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. After measuring reflection coefficients of a device at three different DVC states, the reflection coefficient for all other DVC states can be calculated. Thus, based solely upon three reflection coefficient measurements, the antenna can be tuned to adjust for any changes in impedance at the antenna.
