摘要： A wideband composite right/left handed transmission line (CRLH TL) in conjunction with its corresponding equivalent circuit model is studied based on a cascaded complementary single split ring resonator (CCSSRR). The characterization is performed by theory analysis, circuit simulation, and full-wave electromagnetic (EM) simulation. The negative refractive index (NRI) and backward wave propagation performance of the CRLH TL are demonstrated. For application, a bandpass filter (BPF) with enhanced out-of-band selectivity and harmonic suppression operating at the wireless local area network (WLAN) band is designed, fabricated, and measured by combining the CRLH TL with a complementary electric inductive-capacitive resonator (CELC). Three CELC cells with wideband stopband performance in the conductor strip and ground plane, respectively, are utilized in terms of single negative permeability. The design concept has been verified by the measurement data.
