Abstract

China's UHF RFID band of 840 ~ 845MHz and 920 ~ 925MHz, distance of mobile communication CDMA800, GSM band near, vulnerable to interference in mobile communication system, resulting in demodulation bit error rate increased RFID tags. The interference of mobile communication system formation mechanism analysis, this paper puts forward a design method of UHF mobile communication terminal RFID tag antenna anti interference, deduced the calculation formula of the thickness H of dielectric substrate, and then use HFSS repeated experiments, to determine the dielectric substrate reasonable relative dielectric constant value, loss tangent value , which can design a high gain RFID tag antenna anti interference of mobile communication frequency band. The simulation results show that the, the RFID band return loss values S11 were less than -10dB, the CDMA800 and GSM band return loss values S11 were greater than -10dB, the RFID band Voltage VSWR values were less than 2, the the CDMA800 and GSM band Voltage VSWR values were greater than 2. The RFID tag antenna maximum gain of 7.28dBi, the maximum read distance theory valuation 17.66m.
