Wireless Power Transfer and High Data Rate Communication Using Load-Shift Keying Modulation

In this paper, an optimum broadband Conformal Strongly Magnetic Resonance (CSCMR) is designed which provides simultaneously high efficient power transfer and high data-rate communication through the same link. This wireless power transfer system is able to achieve 20 MHz bandwidth at the operating frequency of 115 MHz maintaining over 80% power transfer efficiency. The integrated planar broadband strongly coupled magnetic resonant system is able to deliver 30% of the given power to a 50 Ω load. Utilizing the large bandwidth, a high data rate digital communication through the same link is achieved, using backscattering modulation. The data transfer is accomplished with 6 Mbps data-rate and 30% overall system efficiency.
