1. A high-Q self-resonant coil, comprising:

  • a high-Q inductor coil, with inductance L, formed on a substrate;

    comprisingat least two turns of formed conducting material;

    wherein a spacing between the at least two turns of the formed conducting material is designed to produce a distributed capacitance, C; and

    wherein a resonant frequency, w, of the self-resonant coil is substantially equal to 1/(LC)1/2;

    wherein w is an operating frequency of a wireless power transfer system.
