基于RFIDUHF频段的车辆防拆无源电子标签分析与设计

Abstract

为更好地将物联网的核心技术rfId应用于智能交通领域,达到更方便、更准确和更快捷地管理车辆的目的,从电子标签的理论开始,论述了电子标签的设计方法,详细分析了电子标签相关的参数,并采用电磁仿真软件HfSS对标签进行了仿真并加工出一款uHf频段rfId车辆无源陶瓷防拆电子标签,该标签已经被中国国家知识产权局认定为实用新型专利,仿真结果与测量结果表明,该标签性能稳定、接收灵敏度高,并且具有防拆性,达到uHf频段rfId电子标签的设计要求。

To achieve the purpose of convenient,accurate and fast vehicles management,and apply RFID,the core technology of IOT,in the field of intelligent transportation,the paper presents a design method of UHF RFID tag,which is a vehicle tamper proof ceramic electronic label based on the theory and design method of tags.A detailed analysis of tag parameters is made in the paper.An UHF RFID tag was produced and identified as patents for utility model by the State Intellectual Property office of China.The simulation results based on the software HFSS verify the effectiveness of the design.The tag has stable performance,higher sensitivity and tamper resistance,and meets the design requirements of the UHF RFID tag.
