Abstract: A method and device for providing impedance tuning to compensate for capacitive loading effects on an antenna which are associated with conductive or physical components in close proximity to the antenna is provided. A dynamic impedance tuning (DIT) controller periodically receives information that indicates that one or more functions of a physical component and/or a particular device operating state are currently active. In response to one or more functions of the physical component being activated, the DIT controller configures the tunable impedance to a pre-set impedance level to compensate for capacitive loading effects on the antenna. In addition, the controller triggers a switch to connect the tunable impedance to the ground signal line to provide antenna tuning corresponding to the preset impedance level. The tunable impedance adjusts the terminal impedance of the ground signal line to minimize capacitive loading effects associated with the signal line.
