Abstract :
Modified Sierpinski fractal based microstrip antenna is designed for ultrahigh frequency (UHF) radio frequency identification (RFID). Combining the techniques of modified fractal shape and corner cutting, the antenna possesses the properties of miniaturization and broad band. The bandwidth is as twice as that of the rectangle antenna and the size is decreased by 10.1% comparing to the rectangle antenna. Simulation results are validated by comparing with experimental measurements. The impedance bandwidth for S(11)<;-10dB of the fabricated antenna whose size is 71×74×3mm3 is 873-923MHz (5.7%). The modified Sierpinski fractal based microstrip antenna is a charming candidate for RFID reader antenna for its miniaturization and wide band.
