Patent ID: 8159090

Claim:
A system, comprising: a transmitter configured to wirelessly transmit a first type of energy and a second type of energy different from the first type of energy; and a receiver including a near field antenna and a far field antenna, the near field antenna configured to receive the first type of energy wirelessly transmitted from the transmitter, the far field antenna configured to receive the second type of energy wirelessly transmitted from the transmitter, the receiver including a first rectification circuit and a second rectification circuit, the first rectification circuit configured to convert the first type of energy received by the near field antenna into usable energy, the second rectification circuit configured to convert the second type of energy received by the far field antenna into usable energy, the near field antenna having an impedance value such that operation of the near field antenna does not interfere with operation of the far field antenna, the impedance value of the near field antenna being associated with impedance matching of the far field antenna to the second rectification circuit, the far field antenna having an impedance value such that operation of the far field antenna does not interfere with operation of the near field antenna, the impedance value of the far field antenna being associated with impedance matching of the near field antenna to the first rectification circuit.
