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

  • a source configured to produce an output electrical signal having a first frequency;

    a non-resonant coupling part, physically connected to said source, said coupling part including a first loop of wire; and

    a resonant antenna part, spaced from said coupling part such that said antenna part is galvanically isolated from said coupling part and is magnetically coupled to said coupling part, said antenna part configured to receive power wirelessly from said coupling part, and said antenna part configured to produce an electromagnetic field based on said power that is wirelessly received, said antenna part comprising a capacitor integrated thereon, and said antenna part configured to resonate at said first frequency.
