<p>Exemplary embodiments are directed to wireless power transfer. A wireless power transfer system include a transmit circuit with a transmit antenna driven from a power amplifier to generate a near field radiation at a resonant frequency within a first coupling mode region surrounding the transmit antenna. One or more repeater antennas are disposed at different locations within the first coupling mode region. Each repeater antenna generates an enhanced near field radiation at the resonant frequency within a coupling mode region corresponding to that repeater antenna. One or more receive circuits including a receive antenna receive power when they are disposed in one of the coupling mode regions corresponding to that repeater antenna.</p> |
