基于三角形Sierpinski微带分形贴片,提出了一种新型的小尺寸领带结RFID标签天线设计。通过仿真,给出了该分形天线的端口特性,同时给出了该领带结型Sierpinski标签天线的谐振频率、方向图以及天线效率。结果表明,采用不同维数的分形结构,可以实现多频段的工作特性,因而该天线可以很方便地应用于RFID电子标签中。
A novel miniaturization bow tie RFID tag antenna is proposed based on the triangular Sierpinski fractal microstrip. The port characteristics of the proposed antenna are presented by simulation. At the same time, the resonance frequency, the radiation pattern and the efficiency of the Sierpinski tag antenna is given. The results of the simulation show that multiple frequency band can be obtained by varying the dimensions of the fractal structure. Hence this kind of antenna can be used into the RFID tag antenna very conveniently.
