Abstract
Methods and apparatuses of a multi-purpose stylus antenna are described. One device includes a processing device comprising a switch, an antenna circuit, and a capacitance sensor. The switch is configured to couple a conductive element between the antenna circuit and the capacitance sensor. The processing device is configured to communicate data to or from a stylus when the switch is coupled to the antenna circuit and to measure capacitance associated with the conductive element when the switch is coupled to the capacitance sensor.
