Composite right left handed transmission line in coplanar configuration

This paper presents a coplanar composite right left transmission line. The later is realized using an elementary cell designed in a coplanar waveguide configuration by combining two distributed passive elements, namely, interdigital series capacitor and two shunt ionductor. A comparative study the coplanar composite right left transmission line with three fingers and five fingers is presented in order to show the effect of increasing the number of fingers in the performance of fingers in the performance of the structure where a great agreement between simulated and theoretical results which validates the theoretical approach.
