DIRECTIVE BEAM OF THE MONOPOLE ANTENNA USING BROADBAND GRADIENT REFRACTIVE INDEX METAMATERIAL FOR ULTRA-WIDEBAND APPLICATION

Directive Beam of the Monopole Antenna Using Broadband Gradient Refractive Index Metamaterial for Ultra-Wideband Application

This paper introduces a novel technique to enhance the gain of the basic monopole antenna by using broadband gradient refractive index (GRIN) metamaterial.The proposed GRIN is designed by using a parallel-line Womens Beanies unit cell metamaterial with different refractive index.A seven GRIN lens is placed on the omnidirectional printed basic monop
