In this paper, a simple design for extending the range of a Wireless Power Transfer (WPT) system is presented. The design consists of a traditional Conformal Strongly Coupled Magnetic Resonance (CSCMR) system that incorporates a repeater resonator, known as the U-loop resonator. Simulated and measured results show that the proposed system with the U-loop provides larger efficiency at transfer distances beyond its original optimal efficiency, achieving a peak efficiency of greater than 70% at a

The proposed system can also maintain efficiencies greater than 60% irrespective of the angular position of the receiver (RX) around the U-loop.
