基于RFID UHF频段的车辆防拆无源电子标签分析与设计

摘要

To achieve the purpose of convenient, accurate and fast vehicles management, and apply RFID, the core tech-nology of IOT, in the field of intelligent transportation, the paper presents a design method of UHF RFID tag, which is a vehi-cle 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 mode] 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 per-formance, higher sensitivity and tamper resistance, and meets the design requirements of the UHF RFID tag.%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.
