Abstract
A non-contact charging device for charging a battery includes a source resonator, a reference antenna, and a variable gain amplifier. The source resonator is configured to transfer electrical energy to a capture resonator in a vehicle. The reference antenna is configured to detect a reference signal originating from the source resonator. The reference antenna is configured to be less sensitive to a presence of a foreign object than a foreign object detection (FOD) antenna proximate to the reference antenna. The variable gain amplifier is configured to amplify a reference signal from the reference antenna.
