中文摘要：

共面波导和分形结构结合应用,在展宽天线带宽方面具有独特优势.提出了一种新型古币形超宽带分形天线,采用共面波导馈电,并加载分形缝隙,天线的阻抗带宽大幅提高.给出了天线的表面电流、回波损耗、方向图和增益结果.对3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2.6～16 GHz,带宽比大于6∶1.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：

CPW and fractal structure used together in antenna design have unique advantages in broadening the bandwidth of the antenna.A novel copper-cash-shaped ultrawideband（UWB） fractal antenna was proposed.By using fractal slot,the CPW-fed antenna had a wide bandwidth.Surface current distribution,return loss,directional patterns and gain of the antenna were investigated.Three iterative fractal antenna was fabricated and measured.The measured results show that the bandwidth is 2.6-16 GHz,larger than 6∶1,and found in good agreement with the simulated results.Thus this antenna can be widely used in compact structure and UWB antenna design.
