射频识别系统通信链路仿真与测试
资料介绍
自由空间下射频识别系统天线通常等效为戴维南等效电路模型,缺少对环境因素和标签电路中寄生元件的考虑。基于射频识别系统基本原理和天线散射理论,提出了一种改进的真实环境下的超高频射频识别系统二端口网络链路模型。建立了基于虚拟仪器技术的射频识别系统天线链路仿真和测试系统。通过仿真实验,得出了真实环境下的标签吸收功率和通信误码率,验证了环境因素对射频识别系统性能的影响
The Thevenin equivalent circuit of RFID system antenna in free space is lack of consideration of environmental factors and tags circuits parasitic components.Based on the basic principle of RFID and antenna scattered theory,an im- proved two-port network link model in real environment of UHF RFID system is proposed.Based on virtual instrument tech- nology,a simulation and test system of RFID system link is established.Through simulation test,the tag’s absorbed power and BER in real environment can be gotten,which validate the environment factors effecting on the performance of RFID system.
