| 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。

| Abstract: | 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. |
