Abstract
A wireless power receiver system includes a receiver antenna including a plurality of receiver coils, each of the plurality of receiver coils configured to receive alternating current (AC) wireless power signals from a wireless power transmission system. The system further includes a receiver controller configured to generate communications signals. The system further includes a plurality of modulation circuits, each of the plurality of modulation circuits operatively associated with one of the plurality of receiver coils and the receiver controller, each of the plurality of modulation circuits configured to partially dampen a magnetic field, coupling the wireless power receiver system with the wireless power transmission system, based on the communication signals provided to each of the plurality of modulation circuits by the receiver controller.
