Summary:
In this paper, an UHF RFID tag antenna for RFID-based blood-bag management system is designed and fabricated. The tag antenna consists of a modified dipole antenna with a reflector, and it is considering high permittivity of blood (εr=60) in the blood bag. The tag antenna is optimized and fabricated with simulations and tests for the cases with/without the reflector, various distance between the reflector and the dipole tag, and the different widths of the reflector. The input reflection coefficient characteristics and the reading range patterns of the tag antennas are measured.
