Abstract

Abstract:

A miniaturization structure of RFID (Radio Frequency of Identification)tag antennas based on Hilbert fractal structure is proposed.Then,the resonant frequencies ,radiation patterns and efficiencies of the tag antennas are simulated by means of MoM (Method of Moment).and a one.dimension tag antenna with Hilbert fractal struc ture is manufactured for test.The simulation and test results show that the space.filling feature of Hilbert fractal
structure antenna can be effectively transformed into the size.reducing feature.and that the RFID tag an tenna with one-dimension Hilbert fractal structure iS of higher emciency

Key words: Hilbert fractal structure, fractal antenna, radio frequency of identification(RFID), tag
