Abstract
The disclosure is directed to a dynamic antenna tuning system for improving wireless links between a host device implementing the system, and one or more other devices. For example, the host device can be a smartwatch or other wearable device, and the other devices can be a pair of wireless earbuds or a smartphone. The antenna tuning system can use both an impedance tuner and an aperture tuner to dynamically tune an antenna based on both the impedance of an antenna at its feed and its radiation pattern. The system can tune the antenna and prioritize multiple wireless links for some devices connected to the host device, over others. The system adjusts tuning parameters in real-time and in response to changes in the connection strength of wireless links between the host device and one or more other devices, for example caused by movement of a user.
