The performance of RFID antennas on metamaterial substrate

This paper introduces a new design to made RFID tags on metamaterial substrate. The metamaterial substrate has a potential to reduce the circuit size of the antenna as well as maintain the performance of the tag made on classical substrate. The behavior of the metamaterial substrate proposed was analysed in terms of S-parameters by commercial simulator to verify its negative permittivity. The simulation result of RFID antenna on metamaterial substrate shown an improvement of the performance compared to the conventional design of the tag antenna, paving the way to the future implementation of these tags.
