摘　　要：本文从工程设计的角度出发,在已经提出的几种左手传输线的基础上,对左手传输线进行了进一步的仿真研究,获得了有利于设计的一些规律。在此基础上,提出了一种变长交指电容的优化方法,将此方法应用到左手传输线的设计中,可以大大减少设计的优化工作量,并且从仿真结果的比较中可以看到该方法能够显著改善左手传输线的通带宽度。In this paper, the left-handed transmission line is investigated by the simulation method from the design point, and some useful design rules are got. Based on this, a new kind of optimized method by changing the length of the interdigital capacitance is presented, and this method could reduce the workload when the left-handed transmission line is designed. From the simulation results, it can be seen that this method can expend the passband of LH TL.
