Abstract: The project involves the exploration of Composite Right and Left Handed (CRLH) transmission line implemented on coplanar waveguide for filter application. Basically composite right and left handed metamaterials exhibit left handed wave propagation at low frequency and right handed wave transmission at high frequency. Metamaterials have wide range of application because of its negative permittivity and permeability characteristics, which contradicts with right-handed conventional materials. Composite Right and left handed Transmission lines are designed by periodically repeating the unit cell which contains series capacitance, series inductance, shunt capacitance and shunt inductance. The dissertation aims is to develop a composite right and left handed transmission line with four unit cell structure to work as a dual band pass filter. The scattering parameters of the implemented structure is studied by using software simulation tool Agilent, Advance design system 2009(ADS) and the corresponding dispersion characteristics of the proposed structure is obtained by compiling with a MATLAB program. The simulation is done with the best knowledge of the software provided. The later stage of the dissertation involves the fabrication of four unit cell transmission line structure. The proposed structure is tested with the help of a Network Analyzer (VNA). The tested results are compared with the simulation results to realize a dual band pass filter.
