摘　　要：为进一步优化ETC系统信号的传输效率和质量,提出对RSU设备中的RFID标签天线进行改进优化,进而提升RFID系统的信号传输水平。其中,对系统的阻抗带宽、天线识别距离、功率反射系数三个参数进行调整优化,并根据改进结果进行标签天线的重新构建。仿真结果表明,与国内的标准ETC系统RFID标签天线相比,设计的标签天线完全满足设计标准,同时具有更高的回波损耗,达到了-35 dB,明显高于标准的-18 dB,这表明该天线具有更好的阻抗匹配情况,能够进行更加准确且稳定的信号传输。综上,设计通过对RFID标签天线的优化,能够有效提升RSU设备中RFID的信号传输质量,具有一定的实际应用价值。In order to further optimize the signal transmission efficiency and quality of the ETC system,the RFID system tag antenna is improved and optimized,thereby enhancing the signal transmission level of the RFID system.Among them,the three parameters of impedance bandwidth,antenna recognition distance,and power reflection coefficient are mainly adjusted and optimized,and the tag antenna is reconstructed based on the improved results.The simulation results show that compared with the domestic standard ETC antenna,the designed tag antenna fully meets the domestic design standards,and also has a higher return loss of-35 dB,which is significantly higher than the standard-18 dB.This indicates that the antenna has better impedance matching,that is,it can perform more accurate and stable signal transmission.In summary,optimizing the tag antenna of the RFID system can effectively improve the signal transmission quality of RFID,and has certain practical application value.
