A repeater for a wireless power transfer system is disclosed. The repeaters includes an elongated strip of material arranged in a substantially circular configuration with opposing ends of the elongated strip disposed in close proximity to each other, an inductive element associated with the elongated strip and arranged to provide a coupling with an adjacent resonator through flux directed outward from a first surface of the elongated strip, and a capacitive element associated with the elongated strip and arranged to resonate electromagnetic energy with the inductive element when the electromagnetic energy is transferred from the adjacent resonator through the coupling provided by the inductive element.
