1. An apparatus for wirelessly receiving energy and data, comprising:

  • a resonator to resonate a first frequency power signal transmitted from a transmission apparatus;

    a radiator to receive a second frequency data signal transmitted from the transmission apparatus;

    a first matching circuit to match input/output impedance for the first frequency power signal upon receiving the first frequency power signal;

    a rectifier to rectify an impedance-matched power signal from the first matching circuit into a DC current;

    a second matching circuit to match input/output impedance for the second frequency data signal upon receiving the second frequency data signal;

    an oscillator to output a second frequency signal by using a first frequency signal output from the resonator as a reference frequency; and

    a mixer to mix an impedance-matched data signal from the second matching circuit with a signal output from the oscillator to restore a baseband data signal.
