摘要
提出了一种新型树状分形天线结构。通过对叶脉进行模拟,天线具有良好的多频特性,二阶分形天线可以在3个频带内良好工作。给出了天线回波损耗、方向图结果。对各阶分形天线进行了加工与测试,仿真结果与测试结果基本吻合,为多频天线的设计提供了新的思路。
A novel tree-shaped fraetal monopole antenna is proposed. Simulation of the nervation shows the antenna has good multi-band characteristics, and the two-iterative fractal antenna can be working in three frequency bands. The return loss and radiation patterns of the antenna are provided and the antennas are fabricated and measured. The measured results are in good agreement with the simulated results. This antenna can be widely used in multi-frequency structure antenna design.
