Abstract :
In this paper, two fractal dipole antennas has been designed and optimized for passive RFID tags at 900 MHz, one based on the 3rd iteration of a modified Koch fractal curve and the other is based on the 3rd iteration of the proposed fractal curve. The designed fractal dipoles have been simulated using IE3D simulator based on Method of Moments (MOM). The simulation showed that the modified Koch fractal dipole has better radiation characteristics and longer read range than the proposed fractal dipole antenna. The two antennas are fabricated using PCB technology and examined in anechoic chamber. The experimental results showed a good agreement with the simulation. The effect of different materials attached to the fabricated antennas is examined.
