Effective Blood Bank Management System based on Chipless RFID

An L-resonator based chipless RFID tag has been introduced in this paper for tracking and identification purposes in a blood bank management system. Four bits of data are being encoded in the unlicensed band between 5.1 to 5.9 GHz, where the first three bits are used to identify the blood group and the fourth bit is used for verification purposes. The proof of concept has been shown by first designing the tag and antenna using CST Microwave Studio and fabricating on a ROGERS RT 5880 and FR-4 substrate, respectively. The tag and antennas have been tested using a Vector Network Analyzer(VNA) and the results reveal good scattering parameter results in the frequency of operation. The compact size of the tag and the antenna, make the overall tag suitable as a smart label in a blood bank management system for use in blood bags and patients.
