Abstract
Systems and methods are disclosed for wireless power delivery that can provide wireless power, via a retrodirective wireless power transfer (WPT) channel, to a wireless power recipient in response to a modulated backscatter signal from a wireless power receiver. A wireless power receiver can produce a modulated backscatter signal and transmit such to a power delivery system to initiate a wireless power transfer linkage. In some examples, a dual-band technique can be implemented where a first band can be used as a dedicated retrodirective WPT channel while a data communication node can utilize a second band for a low energy compatible data communication type. Both a beacon signal (the backscattered signal) for retrodirective linkage at the first band and the communication signals at the second band can be produced via backscattering at the wireless power receiver. A backscattered beacon signal and a communication signal may be modulated and frequency multiplexed.
