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 unit cell metamaterial with different refractive index. A seven GRIN lens is placed on the omnidirectional printed basic monopole antenna. perpendicularly. https://www.hindigyanvishv.com/super-save-Smart-Tv-Led-32-Hd-Panasonic-32fs500b-2-Hdmi-2-Usb-Wi-fi-Conversor-Digital-super-buy/
