摘　　要：改进了一种印刷单极U型微带超宽带天线。利用Ansoft公司的高频仿真软件HFSS对影响其辐射性能的关键参数进行了仿真计算，通过优化使其尺寸减少到原来的22％，阻抗带宽也展宽了24％，最后给出了天线的反射损耗曲线和辐射方向图。天线的-10dB反射损耗的频率覆盖范围为2．3～11．2GHz。这种天线不仅适用于短距离超宽带无线通信，而且也适合于无线局域网（WAN）与蓝牙（BT）通信。An ultra-wideband printed monopole U shape antenna was developed. The key parameters that can influence the radiation performance of antenna were simulated. The proportion was decreased by 78% in optimization, and the impedance bandwidth was increased by 24 %. The reflection loss curve and the radiation patterns of the antenna were given. The reflection loss of - 10dB frequency range was 2.3 to 11.2GHz. This antenna was not only suitable for the currently short-range uhra-wideband communication systems, but also suitable for the WLAN/BT.
