This paper studies the left-handed behavior in conven- tional 2-port coupled line networks. The propagation parameters of 12 periodic structures, each has a difierent coupled line conflguration, have been derived and the left-handed bands have been determined. Two structures were fabricated and measured to conflrm the compos- ite right/left handed (CRLH) characteristics. Measurements and EM simulations were in a very good agreement with the developed theory. In the light of the proposed theory, a geometrical circuit model was also proposed for split ring resonator (SRR). The model is capable to predict its performance over a wide band.
