The source resonator (30) is configured to transfer electrical energy to a capture resonator (20) in a vehicle (12). The reference antenna (52) is configured to detect a reference signal (54) originating from the source resonator (30). The reference antenna (52) is configured to be less sensitive to a presence of a foreign object (36) than a foreign object (36) detection (FOD) antenna proximate to the reference antenna (52). The variable gain amplifier (56) is configured to amplify a reference signal (54) from the reference antenna (52).",
