摘　　要：抗金属标签天线设计是RFID研究的热点及难点,文中设计并研究了一种UHF频段陶瓷基片抗金属标签天线,对天线的回波损耗和阻抗进行了测量,在905-925 MHz内,S_（11）〈-20 d B,在良好匹配的同时还具有全向性辐射的特性,与仿真结果相吻合,而且陶瓷基片保证了良好的耐热性,这意味着天线在恶劣环境下仍能保持良好的性能。The design of anti-metal tag antenna has been a hot spot in RFID research. In this paper, a UHF anti-metal RFID tag antenna on ceramic substrate is designed and investigated. The results shows good impedance matching of S11 〈 - 20 dB of the tag antenna at 905 - 925 MHz, as well as an omnidirectional radiation pattern, which is in agreement with simulation. Besides, the ceramic substrate ensures a high temperature resistance, which implies that the tag can work under tough circumstances while maintaining proper performance.
