Abstract

Abstract: A RFID fractal dipole antenna is designed with the arc of the trigeminal tree structure, which is fed by simple microstrip balun to achieve better impedance matching within employing double parallel line structure and by using the dielectric substrate withε_r=4.4 and tan δ=0.035. The results of electromagnetic property simulation analysis of HFSS show that the return loss can reach 36dB, which is much higher than binary arc-shaped fractal antenna which is 16dB; and the impedance matching is very ideal. By physical processing and testing of the antenna, the measured results are in very good agreement with simulation calculation. Using the space filling of arc fractal structure, the material antenna size is reduced by 80% in comparison with binary arc-shaped fractal antenna. Moreover, the total medium radiation area is relative increased; and the radiation performance is uniform and reliable.
