摘要:

提出了一种新型的带有3.4 GHz和5.5 GHz双陷波特性的超宽带天线。天线由马蹄形的辐射贴片和共面波导馈电的传输线组成。回波损耗<-10 dB的阻抗带宽是3.1~10.6 GHz,除了其中3.3~3.7 GHz 的WiMAX和5.15~5.825 GHz 的WLAN两个陷波频段。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型缝隙来保证。加工和测试的结果表明,天线有着良好的阻抗带宽和全向辐射方向图。

Abstract:

A novel ultra-wideband (UWB) antenna with the 3.4/5.5 GHz dual band-notched characteristics is proposed.The antenna consists of a clevis-shaped radiating patch and a coplanar waveguide (CPW) transmission line.It yields an impedance bandwidth of 3.1~10.6 GHz with return loss S11<-10 dB,except for the two subbands of 3.3~3.7 GHz for WiMAX and 5.15~5.825 GHz for WLAN.These notched subbands are obtained by etching two slits and a U-shaped slot on the radiating patch.The antenna was successfully fabricated and measured,showing broadband matched impedance and a nearly omnidirectional radiation pattern.

Key words: ultra-wideband;dual band-notched;coplanar waveguide-fed;miniaturization , of antenna
