内容简介：根据复合左右手传输线（CRLHTLs）在实现双频微波器件领域的独特优势，设计实现了一个微带结构双频带通滤波器（BPF）。通过设计CRLHTLs的参数，可以任意选取双频滤波器两个通带的中心频率。文中给出了一个中心频率为1．47GHz和2．3GHz的双频带通滤波器设计实例，并通过仿真和实验结果验证设计方法的有效性。利用CRLHTLs设计双频器件，可以在实现双频工作同时保持结构的紧凑性，具有很好的工程应用价值。
Abstract：A dual-band band-pass filter （BPF） using composite fight/left handed （CRLH） transmission lines （TLs） is proposed. By properly choosing the parameters of the CRLH TLs, the ratio of the central frequencies of the two pass band can be arbitrary. A prototype operating at 1.47GHz and 2.3GHz is designed, fabricated and measured. Good agreement between Simulated and measured results demonstrates the effectiveness of the proposed structure. The proposed method can mitigate some of the problems between the dual-band work and the need for compact size, which is useful in practical applications.
