Abstract-This paper presents a closed-form analysis of composite right/left handed transmission lines. The ladder network structure of the transmission line allows to obtain a rational form of any twoport network representation. As a consequence of the rational form of the transfer functions, poles and residues are easily computed and the dominant ones selected leading to an efficient time-domain macromodel. The numerical results confirm the robustness and the accuracy of the proposed method in capturing the physics of composite right/left handed transmission lines.

“…These structures are also known as Generalized Negative Refraction Index Transmission Line (G-NRL-TL) [2,3]. E-CRLH-TLs are metamaterial-based transmission lines, which are, in fact, a hybrid of wellknown Convenient Composite Right-Left Handed (C-CRLH) and Dual Composite Right-Left Handed (D-CRLH) structures [1]. These structures have recently found numerous applications in designing dualand quad-band devices [4][5][6][7][8][9][10][11].…”

Abstract-In this paper, extended composite right/left-handed (E-CRLH) transmission line (TL) metamaterial structures, with two left-handed (backward) and two right-handed (forward) pass bands, are investigated. Also, design procedures in order to design dual-and quad-band E-CRLH-TLs are presented in detail and the parameters of these structures are extracted by clean formulas, while satisfying arbitrary phase shifts at the operating frequencies. Finally, the dispersion and characteristic impedances of these transmission lines are derived and plotted. The results of this paper can be applied to any type of TL-based dual-and quad-band microwave component.

“…Extended composite right/left-handed (ECRLH) transmission lines are extended form of the CRLH transmission lines and can provide two wide bandpass frequency range under a balanced condition in each closed right/left-handed bands, so it can be utilized in designing dual wideband bandpass filters. The idea of such metamaterial transmission lines is proposed in [13] and [14] by combining the conventional CRLH (C-CRLH) and dual CRLH (D-CRLH) unitcell introduced in [15]. For the implementation of an ECRLH transmission line, various design procedures and layouts are proposed in different papers.…”

Abstract-In this paper a miniaturized dual wideband bandpass filter is designed by the modified extended composite right/left-handed transmission line (ECRLH-TL) under balanced conditions in each right/left-hand passbands. A novel equivalent circuit is proposed to provide the design and an implementation of ECRLH unit-cell by means of the complementary, split ring resonator (CSRR) on the ground plane. Since CSRR is utilized as an alternative to implementing one of the resonators of ECRLH unit-cell, the size and complexity of the structure can be consequently reduced. An example of a dual band pass filter with 3 dB frequency bands from 3.2 to 4.8 GHz and from 6 to 7 GHz is investigated. There is a good agreement among circuit, electromagnetic simulations and measured results in both passbands. The measured insertion loss is better than 0.5 and 1 dB in first and second bands central frequency, respectively. The group delay which is an important factor in wideband communications is about 0.62 ns and 0.71 ns, respectively, in the first and second band central frequencies. The final dimensions of the miniaturized filter are reduced to 8.88 mm × 8.18 mm.
