摘　　要： 该文通过仿真研究发现包装箱内容积和物品的等效介电常数是影响包装箱射频识别(RFID)标签天线的两大因素,其中物品的介电常数对RFID标签天线阻抗的影响最大。为了实现通用的"RFID包装箱",设计了一种对包装箱内物品不敏感的纸基RFID标签天线。标签天线采用悬置微带多层介质结构,天线地板面积是辐射单元面积的两倍。仿真和测试结果表明:在多种介电常数的物品包装箱中,此RFID标签天线均较好地与标签IC阻抗匹配。 It is showed by simulation that both the cubage of the container and the dielectric constant of the container materials are the major factors to influence the radio frequency of identification （RFID） tag antenna of container. The dielectric constant of the container materials has more influence on the impedance of RFID tag antenna. For universal ＂RFID container＂, a RFID tag antenna on papery substrate is realized, which is not sensitive to materials of the container. The tag antenna has suspension micro-strip multi-layer structure, and the dimension of antenna ground is doubled as compared with that of antenna radiating element. The simulation results show that the RFID tag antenna match impedance well with the RFID tag IC for several containers with different dielectric constants.
