1. A transmitter system for transmitting wireless electrical power, comprising:

  • a source which creates an output electrical signal having a specified frequency;

    a coupling part, directly connected to said source, said coupling part formed of a first loop of wire which is impedance matched to said source; and

    an antenna part, spaced from said coupling loop such that it is not directly connected to said coupling part, but magnetically coupled to a magnetic field created by said coupling part, said antenna part having no wired electrical connection thereto and receiving power wirelessly from said coupling loop, and said antenna part creating a magnetic field based on said power that is wirelessly received, said antenna part formed of an wire coil having an inductance L, and a capacitor having a capacitance C, and said antenna part having an LC value which is substantially resonant with said specified frequency.
