摘要
采用在单极子天线顶部加载印制Peano分形结构和短路探针的方法,缩小了单极子天线的尺寸,展宽了阻抗带宽。印制Peano分形单极子天线具有结构简单,容易实现和无需额外的阻抗匹配网络等优点。在分析研究分形曲线迭代阶数、地板尺寸、微带线宽、探针尺寸以及天线高度对天线性能影响的基础上,设计并研制了UHF频段的印制Peano分形单极子天线。仿真和实测数据表明该天线电压驻波比小于2的相对阻抗带宽达到了14.1%,而其电尺寸仅为λmax/14。
To compress the dimension of the monopole antenna and to enhance its impedance bandwidth, this paper presents a technique of loading printed Peano fractal structure and posts to the top of the monopole antenna. The geometrical structure of the printed Peano fractal monopole antenna is simple and is easy to be realized. Its impedance bandwidth is wider without additional impedance matching network. The effects of the order of fractal curve, the dimension of ground plane, the width of microstrip line, the thickness of post and the height of the antenna are analyzed. Printed Peano fractal monopole antennas in UHF band are designed and fabricated. The simulated and measured data show that the relative impedance bandwidth （voltage standing wave ratio is less than 2） of the antenna achieves 14.1% and the electrical length of the antenna is only λmax/14.
