小型化超宽带印刷单极子天线

内容简介：该文提出一种小型化超宽带印刷单极子天线，阻抗带宽为3．17～50GHz。该天线采用圆彤单板子为辐射结构，利用共而波导馈电方式．天线的尺寸为30×32×1．6mm，通过适当地调整板尺寸和阋形辐射单元的半径，可以使天线得到很好的阻抗匹配。与以往的天线相比，带宽更宽，尺寸更小，天线具有良好的辐射性能，达到了小型化的婪求．可为将来的超宽带通信应用提供良好的选择。

Abstract：This paper presents a miniaturized ultra-wideband printed monopole antenna,impedance bandwidth of 3.17 -50GHz.The antenna adopts a circular monopole radiation structure,using coplanar waveguide feeding mode,the antenna size is 30 ×32 × 1.6mm,by appropriate adjustment of the floor size and circular radiation unit radius,can make the antenna has very good impedance matching.Com- pared with previous antenna,widening the bandwidth,smaller size,the antenna has good radiation per- formance,achieving miniaturization requirements,can provide future ultra wideband communication application to provide a good choice.
