摘要
针对用于IT设备资产管理的RFID系统存在读取率低、读取范围小、易受干扰的问题,设计了一种具有抗金属、抗移动通信终端干扰、高增益的双频微带天线。HFSS仿真结果显示,标签天线在CDMA800和GSM的UHF频段S11值大于-10 dB,天线最大增益为7.28 dBi,标签最大读取距离理论估值为17.66 m。设计的RFID标签天线适应IT设备资产管理环境特殊要求。
A dual-band microstrip antenna with the characteristics of resistant metal,anti mobile communication terminal interference and high gain was designed to overcome low reading rate,small read range and vulnerable to interference shortco-mings existing in the RFID system applied to IT asset management. The HFSS simulation results show that,in CDMA 800 and GSM UHF bands,the S11 value of tag antenna is greater than -10 dB,the antenna maximum gain is 7.28 dBi and the theoreti-cal estimation value of label maximum read distance is 17.66 m. RFID tag antenna design can meet the special requirements of IT asset management.
