Abstract: A wireless power transmission system includes a transmission antenna that has a source antenna coil and an internal repeater coil. The system further includes two demodulation circuits, for demodulating incoming communications from a power receiver. One demodulation circuit receives sensed signals at the source coil and the other receives sensed signals at the internal repeater coil. The pair of sensed signals are then summed at a summing amplifier to generate a communications signal for input to a controller of the wireless power transmission system.
