| 摘 要： | 提出了一种新型的具有三陷波特性的超宽带印刷天线。大钱形的辐射贴片和共面波导传输线馈电,可以保证在相当宽的3个频带内具有良好的阻抗匹配。回波损耗S11＜-10 dB的阻抗带宽是3.1~10.6 GHz,除了其中3.3~3.7 GHz 的WiMAX,5.15~5.825 GHz的WLAN和7.25~8.4 GHz的X波段下行频段3个陷波频段。这些陷波的频段可以通过在天线的辐射贴片上增加长条裂缝和U形缝隙实现。加工和测试结果表明,该天线具有很好的阻抗带宽和全向辐射方向图。

| Abstract: | A novel printed ultra-wideband (UWB) antenna for triple-band notched characteristic is proposed.Good impedance matching in a wide triple-band can be achieved by a copper coins shaped radiating patch and a coplanar waveguide (CPW) transmission line.It yields impedance bandwidth of 3.1~10.6 GHz with return loss S11<-10 dB,except for the three subbands of 3.3~3.7 GHz for WiMAX,5.15~5.825 GHz for WLAN and 7.25~8.4 GHz for downlink of X-band.These notched subbands are obtained by etching slits and U-shaped slots on the radiating patch.The antenna was successfully fabricated and measured,showing broadband matched impedance and nearly omnidirectional radiation pattern. |
