摘要文章基于负折射周期电路结构,设计了一种宽带的类螺旋天线结构.该天线由两层介质板以及在其上构建的六个形似工字的谐振单元组成,通过50欧姆同轴馈电.相对螺旋天线,它构建更加方便.仿真和测试结果表明这种天线相对带宽高达30%以上,在频带宽度内有类似螺旋天线的三个辐射模式出现,增益均在5dB以上,其中中间模式具有全向辐射特性. Based on negative refraction circuit mode,A novel broadband analogy-helix antenna feeding by 50 ohm coaxial-line is proposed in this paper,Which is constructed by two layer substrates and six resonance cells being printed on it.Compared to helix antenna,the construction method is more convenience.Measured and simulation results shows that the bandwidth can achieve 30percent,three radiation modes of helix antenna appeared in the bandwidth,and the maximum gain can achieve 5dB.
