Abstract
This work is dealing with the principle of modelling a 2-D metamaterial reflector lens antenna used as a communication device. The lens antenna is consisting of low loss with wideband E-shaped metamaterial resonators (ESR) and the parabolic reflector. The metamaterial structure shows a negative refractive index (NRI) behaviour to a normally incident wave. The numerical simulation has been carried out using CST microwave studio (MWS) 3-D simulator. The main idea of this present work is to investigate the focusing effect of the planar metamaterial lens and to enhance the radiation pattern by reducing the sidelobe levels and increasing the main lobe level. The simulated results of both far-field and near-field radiation patterns in wider bandwidth, showing high directivity and gain upto 18dBi is achieved.
