Abstract: A detection device is provided. The detection device includes a transmitter and a detector. The transmitter supplies an induced current to an antenna and to adjust a strength of an induced voltage generated in the antenna by adjusting the induced current. The detector monitors the strength of the induced voltage of the antenna and generates a control signal for controlling the induced current to the antenna based on the monitored strength of the induced voltage of the antenna.
