| 摘 要： | 设计了一种带有2个陷波频段的超宽带天线。天线的缝隙和馈电枝节采用相反的梯形结构,以实现较好的阻抗匹配。通过在宽缝隙中增加2个线形枝节和1个"E"形结构,使得天线在3.0 GHz~3.9 GHz和5 GHz~6 GHz 2个频段内出现频率阻断。根据天线的阻抗曲线,给出等效谐振电路并对陷波产生的原理进行了分析。最后对天线的远场辐射特性进行分析和阐述,测试结果良好,达到了陷波超宽带天线频率阻断的效果。

| Abstract: | A planar ultra-wideband antenna with dual band-notched characteristics is proposed.Using a broad trapeziform slot at the bottom of radiating patch and an inversed trapeziform shaped feeded metal stub,good impedance match can be achleved.Introducing two linear shape and one E-shaped metal stubs in the broad slot,dual band-notched characteristics can be created within the frequency range between 3.0 GHz~3.9 GHz and 5 GHz~6 GHz.The equivalent electrocircuit can be drawn according to the impedance curve,analysi... |
