| 摘 要： | 提出一种新型的小型超宽带（UWB）宽缝天线，并对其进行带阻功能设计.该天线采用椭圆结构的调谐支节，并由共面波导进行馈电.为获得超宽带工作特性，将其辐射缝隙设计为对称多边形.对该天线的性能进行仿真和实验研究，实测结果表明，该天线的-10 dB反射损耗频率范围为3.2~10.1 GHz.另外，通过在椭圆支节上开W形槽，使天线实现对无线局域网（5.150～5.825 GHz）频段的带阻功能.

| Abstract: | A novel compact wide-slot planar antenna and its extended design with band-notched function are proposed for ultra-wideband (UWB) applications. The antenna is fed by coplanar wave guide (CPW) with an elliptical tuning stub. A symmetric polygonal wide-slot configuration is used to obtain ultra-wideband characteristics. The characteristics of the proposed antenna are investigated both numerically and experimentally. Experimental results show that the impedance bandwidth of the antenna reaches up to 3.2~10.1 GHz for S11≤-10 dB. In addition, by inserting W-shaped slots on the elliptical stub, band-notched function of the antenna is achieved for WLAN (5.150～5.825 GHz) applications. |
