首先采用递归法构造了一种新型的分形结构,并利用其设计了分形印刷折合振子,然后对传统印刷巴伦进行了结构调整,有效地缩减了馈电电路的物理尺寸.使用Ansoft HFSS和Serenade软件对天线进行仿真优化,制作了实物并完成实验测量.仿真结果和测量数据表明:该新型分形印刷折合振子的横向尺寸较传统的半波印刷振子能够缩减68%,这与Hilbert分形印刷折合振子比较,具有良好的尺寸缩减性.

[Abstract]
Technique of recursion is introduced to construct a novel fractal structure at first,and a fractal printed folded dipole which uses the fractal structure is designed.After that,the structure of traditional printed balun is modified to reduce the dimension of the feed network.The antenna is simulated and optimized by Ansoft HFSS and Serenade,then the fractal antenna is fabricated and measured.The characteristics of this fractal antenna is obtained by simulated results and experimental data which show that th...
