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.
