Abstract:

In order to match the Radio Frequency Identification（RFID） tag antenna with the tag integrated circuit（IC） impedance,a microstrip parasitic structure of RFID tag antenna on papery substrate is proposed.Moreover,the effects of structure changes of antenna array on the impedance and radiation patterns of the tag antennas are simu-lated via the method of moment and a microstrip parasitic RFID tag antenna with meander-line structure is manu-factured.Simulation and test results indicate that the combination of the meander-line and the parasitic structures helps to obtain the RFID tag antennas with small real resistance and large imaginary reactance.

Key words: papery substrate, radio frequency identification, tag, parasitic antenna
