A Frequency Domain 8-Bit Chipless RFID tag for IoT and Sensor Applications

The most anticipated automatic tracking and tagging technology that has emerged in monitoring and locating things in real time over the past decades is Chipless Radio Frequency Identification Technology, whose interrogating signals are electromagnetic. The tag proposed in this paper combines a split ring with hexagonal-shaped resonators. The tag is modeled on FR4 substrate (εr=4.4, tan (j=O.02) having a thickness of 1.6mm which works on frequencies from 1.73GHz to 7.98GHz that helps in IOT and sensor applications. The tag is simulated using CST software and the results are analyzed for the IoT and Sensor applications.
