Abstract:
Exemplary embodiments include an antenna for receiving electromagnetic radiation in a broadcast radiation band and a near-field radiation band to generate a Radio Frequency (RF) signal. A coupling element couples the RF signal to a first port and at least one additional port, which may be a second port and a third port. A wireless power receiver on the first port includes a rectifier for converting the RF signal to a DC signal when the antenna couples to radiation in the near-field radiation band in a coupling-mode region of the antenna. A near-field communication transceiver includes circuitry for communicating information on the antenna in the near-field radiation band when the coupling element couples the second port to the RF signal. A broadcast receiver on the third port includes circuitry for receiving and tuning the broadcast radiation band when the coupling element couples the third port to the RF signal.
