Patent ID: 7516057

Claim:
A method for optimizing the design parameters of an RFID tag for use with a RFID reader in a RFID system based on selected design constraints, the method comprising the steps of: receiving a first desired frequency band that the RFID tag will operate in; receiving a first desired data range between the RFID tag and the RFID reader; receiving a first desired cost for the RFID tag; receiving a first desired data rate for the RFID tag; receiving a first desired operating voltage for the RFID tag; receiving a first carrier modulation period of an interrogation signal generated by the RFID reader within a range of carrier modulation periods, wherein the range of carrier modulation periods is constrained by each of the first desired frequency band, the first desired data range, the first desired cost, the first desired data rate, and the first desired operating voltage; varying an antenna capacitance of the RFID tag to a desired first capacitance value in conjunction with the first carrier modulation period to generate a first plurality of operating data rates for the RFID tag; selecting a first operating data rate of the RFID system, the first operating data rate being the operating data rate of the first plurality of operating data rates nearest to the first desired data rate; calculating a first operating data range based on the first desired operating voltage and the first operating data rate; and displaying a representation of the first operating data rate and the first operating data range.
