1. A multi-mode radio frequency identification (RFID) reader comprises:

  • a baseband processing module coupled to;

    convert outbound data into outbound modulation information; and

    convert an encoded inbound signal into inbound data;

    a transmitter section coupled to convert the outbound modulation information into an up-converted outbound signal;

    a far field antenna structure;

    a near field coil structure;

    a transmit multiplexer coupled to output the up-converted outbound signal to the near field coil structure when the multi-mode RFID reader is in a near field mode and to output the up-converted outbound signal to the far field antenna structure when the multi-mode RFID reader is in a far field mode;

    a receive multiplexer coupled to input an inbound signal from the near field coil structure when the multi-mode RFID reader is in the near field mode and to input the inbound signal from the far field antenna structure when the multi-mode RFID reader is in the far field mode; and

    a receiver section coupled to down-convert the inbound signal into the encoded inbound signal.
