1. A method for optimizing the design parameters of an RFID tag for use with a RFID reader in a RFID system, the method comprising the steps of:

  • selecting a desired frequency band that the RFID tag will operate in;

    selecting an acceptable minimum range between the RFID tag and the RFID reader;

    selecting a maximum acceptable cost for the RFID tag and a minimum acceptable data rate for the RFID tag. selecting a minimum operating voltage for the RFID tag;

    calculating an optimal data rate by varying a carrier modulation period of an interrogation signal generated by the RFID reader and an antenna capacitance of the RFID tag; and

    calculating an optimal range for a given operating voltage and the calculated optimal data rate.
