| 摘 要： | 该文使用两种全波分析法对传统的带阻滤波器和一维复合左右手传输线(Composite Right/left-handed Transmission Line CRLH-TL)进行了数值分析,解决了多端口激励源的设置和多端口S参数提取的两大难点,计算结果分别与FEKO和电路模型等效法的分析结论进行了比较,吻合较好;并通过增加CRLH单元数得出电路模型等效法的不足,不仅验证了此激励源设置和S参数提取的正确性,也得出了CRLH-TL不同于传统右手传输线的一些左手特性,为分析、优化CRLH传输线以及CRLH漏波天线提供了一定的理论支持。

| Abstract: | In this paper,a conventional band-stop filter and a 1D-CRLH-TL are analyzed by two kinds of full wave methods.And these methods can be applied to set the excitation in MoM and extract S-parameters in EM computation procedure.The numerical results are in good agreement with those achieved by FEKO and equivalent circuit model.And the insufficiency of equivalent circuit model is gained by increasing the cell of CRLH-TL.Not only the correctness of the source excitation and the S-parameters extraction is validated,but also some special left-hand characteristic of CRLH-TL is obtained.This research provides some theoretical guidance for analyzing and optimizing the CRLH-TL and CRLH leaky-wave antennas. |
