| 摘 要： | 研究了不同角度、不同阶数的基于Koch曲线的天线性能,仿真和测试结果表明,在保持天线长度不变的条件下,随着角度和阶数的增加,天线的谐振频率下降,而天线的方向图依然具有半波振子的低方向性。在此基础上,综合Koch和Hilbert曲线,设计了一款尺寸为55mm×10mm的小型化电子标签。该标签天线不仅具有半波阵子的低方向性,而且简单、便于调谐。

| Abstract: | The paper present how the iteration number and angle affect the characters of tag antenna based on Koch curve. The simulation and test result show that the resonant frequency would decrease with the iteration number and angle increasing on condition that the height of tag antenna is not changed. Besides, the radiation pattern is consist with dipole, namely, it is omni-direction. Based on this result, a tag antenna based on Koch and Hilbert curve is designed. The size of tag antenna is 55mm × 10mm. The tag antenna is not only omnidirection, but also simple, convenience and tuning conveniently. |
