Abstract
A mixed antenna system driving method for driving a mixed antenna consisting of a control IC, a sensor module and an antenna is disclosed. The control IC switches the antenna to a capacitive proximity sensor of the sensor module for enabling the capacitive proximity sensor to sense the approaching of an external object by means of the antenna, and then switches the antenna away from the capacitive proximity sensor to an electromagnetic wave generating circuit of the sensor module for enabling the electromagnetic wave generating circuit to perform an induction operation by means of the antenna after received a sensed signal from the capacitive proximity sensor, and switches the antenna back to the capacitive proximity sensor after the induction operation of the electromagnetic wave generating circuit.
