文章基于LS文法构建的Sierpinski曲线应用于射频识别(RFID)标签天线的设计。首先通过EM仿真得到了Sierpinski曲线分形天线的谐振频率、回波损耗、驻波比、增益与分形级数的关系,然后利用二级和三级Si-erpinski曲线分别设计了工作频率在915 MHz的RFID标签天线。仿真结果表明,Sierpinski曲线分形天线的自相似特性和空间填充特性可有效转化为标签天线的尺寸缩减特性,其辐射增益表明该结构适合RFID标签天线的要求。
The Sierpinski curve based on LS grammar is applied to the design of radio frequency identification (RFID) tag antenna. Firstly, the relationship between the resonance frequency, return loss, VSWR, gain and fractal series of Sierpinski curve fractal antenna is obtained by EM simulation. Then the second and third order Si-erpinski curves are used to design the operating frequency of 915 MHz RFID tag antenna. The simulation results show that the self-similar and space-filling characteristics of the Sierpinski fractal antenna can be effectively converted into the size-reducing characteristic of the tag antenna. The radiation gain shows that the structure is suitable for the RFID tag antenna.
