Abstract

A wireless transmission system for transmitting AC wireless signals includes a transmission controller configured to provide first driving signals for driving the first transmission antenna. The wireless transmission system further includes a power conditioning system configured to receive the driving signals, receive input power from an input power source, and generate the AC wireless signals based, at least in part, on the first driving signal and the input power source. The wireless transmission system further includes a first transmission antenna configured for coupling with one or more other antennas and configured to transmit the AC wireless signals to the one or more other antennas, receive the AC wireless signals from one or more other antennas, and repeat the AC wireless signals to the one or more other antennas.
