Methods, systems, and computer program products are provided for dynamically reconfigurable tuning for wireless power and data communications. A wireless charging (WLC) device may improve the efficiency of variable power and data communication to a chargeable device with variable relative positioning and coupling in 3D space by dynamically reconfiguring transmitter tuning. A WLC transmitter may be dynamically reconfigured (e.g., between symmetric and asymmetric antenna impedance matching) based on at least one of the type of wireless transmission or a wireless transmission efficiency for the type of wireless transmission. For example, the controller may dynamically select a configuration for wireless power (e.g., or data) transmission based on the most efficient configuration determined from dynamically measured efficiencies for asymmetric and symmetric wireless power (e.g., or data) transmission. Tuning may be dynamically reconfigured, for example, by controlling an automatically variable inductor (e.g., comprising at least one ring switch) to automatically vary inductance.
