Abstract
The present disclosure generally relates to a device having a capacitance sensor that detects a change in capacitance that occurs in the antenna whenever the antenna is in close proximity to a user's hand and/or head. Following detection of the capacitance change, the capacitance of the antenna may be changed by using a variable capacitor that is coupled to the sensor through a controller.
