基于方形螺旋谐振器的紧凑型RFID标签天线
Compact RFID tag antenna based on square spiral resonator
摘要
Abstract
A miniaturized ultra-high frequency(UHF)radio frequency identification(RFID)tag antenna was designed.The antenna was composed of two square spiral resonators shorted inside and outside.By adjusting the edge length of the outer ring spiral resonator and the spacing between the inner and outer ring spiral resonators,the resonant frequency of the proposed tag antenna could be effectively tuned.The simulation results show that the proposed tag antenna has good impedance matching and the frequency band range covers the whole UHF band(840～960 MHz).It has a dimension of 7.60 mm×7.60 mm×0.05 mm,which is 96%smaller than the traditional spiral resonator(SR)antenna.The measure result shows that the proposed tag antenna achieves the maximum reading distance at 910 MHz in 4 W effective isotropic radi-ated power.The proposed UHF RFID tag antenna has some advantages of small size,wide frequency band,low cost and easy batch fabrication,and is suitable for applications with small size requirements.关键词
