1. A system comprising:

  • a wideband antenna configured to receive wireless signals from at least a first type of signal source configured to transmit in a first frequency band, and at least a second type of signal source configured to transmit in a second frequency band, different from the first frequency band;

    a first circuitry branch including;

    a first bandpass filter configured to pass at least a portion of the first frequency band;

    a first matching network coupled to the first bandpass filter; and

    a first rectifier coupled to the first matching network;

    a second circuitry branch including;

    a second bandpass filter configured to pass at least a portion of the second frequency band;

    a second matching network coupled to the first bandpass filter; and

    a second rectifier coupled to the first matching network, wherein outputs of the first and second rectifier are configured to couple in series to an output;

    a first switch positioned to disconnect the first rectifier from the output when a voltage provided by the first rectifier is below a first threshold; and

    as second switch positioned to disconnect the second rectifier from the output when a voltage provided b the second rectifier is below a second threshold.
