【摘要】 本文主要研究左手传输线的零相位特性。由于减小左手单元的寄生参量能增大零相位传输带宽,因此分别对电感和电容进行建模和精确的等效电路参数提取。在参数提取过程中,提出了缺陷地电感模型,减小了电感的寄生电容参量。最后建立一个左手传输单元和左手传输线,结果显示缺陷地电感使得传输带宽得到了一定增大。为今后的超宽带零相位左手传输线的研究打下了基础。更多还原

【Abstract】 This paper focus on zero-degree left-handed transmission lines. As the reducing of left-handed unit’s parasites can widen the bandwidth of zero-degree propagation, the modeling of inductor and capacitor and the accurate parameter extracting of the equivalent circuit are presenting in this paper, respectively. During the process of parameter extracting, a new inductor mode with defected ground is represented. Finally, a left-handed transmission unit and a two-units transmission line are set up, and the simulating results show that the propagation bandwidth with defected ground is widened.更多还原
