【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(WLAN)与蓝牙(BT)通信。更多还原

【Abstract】 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 ultra-wideband communication systems,but also suitable for the WLAN/BT.更多还原
