摘要:

摘  要:本文提出了一种三陷波特性超宽带天线的设计方法。该天线以圆形的单极子天线为原型采用共面波导互耦的馈电方式。天线的辐射频率覆盖的带宽在2.4G Hz~15.1 GHz,其相应的回波损耗大于10 dB。通过在圆形单极子天线中嵌入互耦环缝谐振器(CSRR)实现超宽带的陷波特性。文中在3.3 GHz~4.4 GHZ,5.25 GHz~5.87 GHZ,11.61 GHz~12.63 GHz的三个频段实现了陷波,可以避免超宽带频段与其他频段之间的干扰。而且超宽带天线(UWB)具有良好的全向辐射特性。

Abstract: A design method of three notch for ultra-wideband antenna (UWB) is presented in this paper. Circular monopole antenna as the prototype of the ultra-wideband antenna, a coplanar-waveguide (CPW) coupled-fed is applied in the antenna. The antenna has a large bandwidth covering the frequency band from 2.4 GHz - 15.1 GHz with return loss larger than 10 dB. Notch characteristics is achieved by complementary split-ring resonator (CSRR) embedded in the circular monopole antenna. Multi-notch is implemented in 3.3 GHz to 4.4 GHZ, 5.25 GHz - 5.87 GHZ, 11.61 GHz - 12.63 GHz. Thus avoiding interference between the band and other bands of ultra-wideband, and the ultra-wideband antenna has a good omni-directional radiation.
