A PASSIVE RADIO-FREQUENCY IDENTIFICATION (RFID) TAG AND A METHOD OF OPERATING THE SAME

摘要

ABSTRACT OF INVENTION A PASSIVE RADIO-FREQUENCY IDENTIFICATION (RFID) TAG AND A METHOD OF OPERATING THE SAME The invention relates to Radio Frequency Identification (RFID) tags. According to one embodiment of the invention, a passive RFID tag (100) comprises: a non-uniform transmission line (1002) made of a microstrip transmission line to store information in form of UWB pulses; and an ultra-wide band tag antenna (1001) integrated with a first port (1004) of the non-uniform transmission line (1002) to communicate the stored information to a RFID reader (2001) device. According to another embodiment of the invention, a method of operating a passive RFID tag (100) comprises: communicating information stored in form of UWB pulses on the microstrip non-uniform transmission line (1002) of the passive RFID tag (100) to the RFID reader (2001) device through the ultra-wide band tag antenna (1001) of the passive RFID tag (100), wherein the ultra-wide band tag antenna (1001) is integrated with the first port (1004) of the microstrip non-uniform transmission line (1002).
