UHF-RFID Tag Design for Improved Traceability Solution for workers' safety at Risky Job sites

Tracking and monitoring workers in large job sites is a difficult job. Therefore, RFID technology may be the solution to reduce down the time to monitor the workers and obtain the related information. UHF RFID technology has the advantage of reading from a farther distance beside the provision to store information about the tagged worker offering a better reliable solution for their traceability and safety. Here, a UHF RFID tag antenna is proposed to develop an " IoT enabled RFID system" for the monitoring of workers. The designed tag has a simple structure and does not require any metallic vias. The proposed tag exhibits a perfect conjugate match to that of the integrated Higgs-4 chip in the European band. The tag is first designed for free space and then optimized to work on a worker's helmet with a read range of 4.6 meters.
