摘 要: 提出了一种基于H ilbert分形结构的射频识别(RFID)标签天线的尺寸缩减设计.通过矩量法仿真,给出了H ilbert标签天线的谐振频率、方向图以及天线效率,并制作了一维H ilbert标签天线实物进行测试.仿真和实测结果表明,H ilbert分形结构天线的空间填充特性可有效转化为标签天线的尺寸缩减特性,而且一维H ilbert标签天线具有更高的天线效率. A miniaturization structure of RFID (Radio Frequency of Identification) tag antennas based on Hilbert fractal structure is proposed. Then, the resonant frequencies, radiation patterns and efficiencies of the tag antennas are simulated by means of MoM ( Method of Moment), and a one-dimension tag antenna with Hilbert fractal structure is manufactured for test. The simulation and test results show that the space-filling feature of Hilbert fractal structure antenna can be effectively transformed into the size-reducing feature, and that the RFID tag antenna with one-dimension Hilbert fractal structure is of higher efficiency.
