Abstract: A radio frequency identification (RFID) tag. In one embodiment, an RFID tag includes an integrated circuit die. The integrated circuit die includes circuitry configured to store information and transmit the stored information responsive to reception of a radio frequency (RF) signal. The integrated circuit die also includes an antenna coupled to the circuitry. The antenna is configured to transmit and receive RFID signals. Further, the antenna and the interconnects of the circuitry are formed of a same metal, and fabricated using a same semiconductor process.

Abstract: A radio frequency identification (RFID) tag. In one embodiment, an RFID tag includes an integrated circuit die. The integrated circuit die includes circuitry configured to store information and transmit the stored information responsive to reception of a radio frequency (RF) signal. The integrated circuit die also includes an antenna coupled to the circuitry. The antenna is formed as a loop antenna array configured to transmit and receive RFID signals. Further, the RFID tag includes a first test pad and second test pad formed on the integrated circuit die with the first test pad coupled to a first end of the antenna by a first interconnect and a second test pad coupled to the second end of the antenna by a second interconnect.
