摘　　要：设计了一种共面波导馈电超宽带天线。该天线在单层覆铜介质基板上通过酸蚀制得,介质基板尺寸为26.0mm×29.0mm×1.5mm,材料是相对介电常数为4.4的FR4,利用仿真软件HFSS对天线参数进行仿真和优化。结果表明,通过在共面波导地面上刻蚀对称结构的多边形槽,天线频带宽度达到2.8～10.5GHz(S11≤-10dB),相对带宽达116%,该天线具有良好的方向图和增益性能,满足超宽带天线性能要求。A CPW-fed ultra-wideband antenna was designed.The antenna was etched on a 26.0 mm× 29.0 mm×1.5 mm single-layer copper-cladding substrate of FR4 with relative permittivity of 4.4,.The parameters of the antenna were simulated and optimized with HFSS.The results show that the bandwidth（return loss≤-10 dB） covers 2.8～10.5 GHz range,which means a relative bandwidth of 116% by a symmetrical polygon notch cut in the ground of the CPW.The antenna has good gain and radiation performance and meets the requirements of the ultra-wideband antenna.
