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。

关键词: 分形天线树状分形分形阶数多频特性小型化

Abstract:

A novel treeshaped fractal monopole antenna is proposed. Simulation of the nervation shows the antenna has good multiband characteristi cs，a nd the twoiterative fractal antenna can be working in three frequency bands. T he r eturn loss and radiation patterns of the antenna are provided and the ante nnas are fabricated and measured. The measured results are in good agreem ent with the simulated results. This antenna can be widely used in multif requency structure antenna design.

Key words: tree shaped fractal fractal dimension multi-band characteristic miniaturizati on
