1. A wireless power system, comprising:

  • a magnetically resonant antenna including an inductor having a variable inductance and a capacitor, having a variable capacitance;

    a power conversion circuit, coupled to said magnetically resonant antenna, and connecting with a magnetically resonant wireless power via said antenna, said circuit determining a measure of wireless power transfer, and producing a control signal indicative of said measure about how well information from said wireless power is being coupled, and provides a control signal to said magnetically resonant antenna, and wherein said magnetically resonant antenna adjusts at least one of said inductor and said capacitor value based on said signal.
