Based on Hilbert theory and technique, a folded tag antenna for RFID application is presented in this paper. In order to reduce the size of tag, a Hilbert fractal structure is employed. Additionally, to match flexibly the impedance between antenna and chip, a folded technique is employed. The input impedance of tag antenna can be adjusted easily by changing the high of folded structure. A designed tag antenna dimension is 23.32mm×7.66mm, and its return loss, bandwidth, gain and theoretical detection distance are given at 2.45GHz by HFSS software. The simulation results show that the designed antenna can meet the requirements of the practical applications.
