Design of Metamaterial Based Patch Antenna for Gain Enhancement

Metamaterial structure is used for the gain enhancement of the patch antenna operating in L-band. The demand for high gain equipment is of great interest, devises that are used in day-to-day life such as smart phones, handheld tablets and wireless internet devices needs high gain antennas. The slotted double circular structure acts as metamaterial to enhance the gain of the patch antenna. The metamaterial structure enhances the gain of the patch antenna by reducing the beam width in the operating frequency band.
