中文摘要：

提出了一种新型树状分形超宽带天线。采用共面波导馈电，通过加载分形缝隙，使天线的阻抗带宽大幅提高。给出了天线回波损耗、方向图和增益结果。对2阶分形天线进行了加工与测试。测试结果表明，天线带宽达到3．5～8GHz，相对带宽为70％。仿真结果与测试结果基本吻合，为超宽带小型化天线的设计提供了新的思路。

英文摘要：

A novel tree-shaped fractal UWB antenna is proposed. By using fractal slot, the CPW fed antennas has a wider bandwidth. Return loss, radiation patterns and gain of the antenna are investigated. Two-iterative fractal antenna is fabricated and measured. Measured results show that the bandwidth covers from 3.5 GHz to 8 GHz and the relative bandwidth is 70%. Simulation results and the measure results agree with each other well. Thus this antenna can be widely used in compact structure and UWB antenna design.
