摘要

The new concept of dual extended composite right/left-handed transmission linern(D-ECRLH TL), with 2 right handed and 2 left handed frequency bands is presented.rnThe D-ECRLH TL and extended composite right/left handed transmission line arernstructurally dual. Therefore, the proposed TL shows the dual properties of thernECRLH TL. The D-ECRLH indeed behaves as a dual-band bandstop filter, in oppositionrnto the ECRLH which is a dual-band bandpass one. In contrast, the D-ECRLHrncreates an unlimited LH bandwidth. In this article, the transmission parameters andrnthe fundamental properties of the D-ECRLH TL (dispersion and impedance diagrams)rnare investigated. The results show that the proposed structure is suitable torndesign the quad-band microwave circuits and systems. A prototype of the proposedrnD-ECRLH unit cell is realized by the microstrip technology. The good agreementrnbetween the measurement and simulation results confirms the realizability of the proposedrnstructure.
