Abstract :
In this work, a Quasi-Yagi antenna is designed to operate at 2.4 GHz for RFID applications. The proposed device is composed by a Quasi-Yagi antenna surrounded by fractal metamaterial structures placed at strategic positions, improving bandwidth and enhancing the antenna tunability at a desired frequency. Design guidelines for the combination of fractal structures and the Quasi-Yagi antennas are presented. The obtained results show that the use of the proposed antenna in RFID systems is very promising.
