Abstract

This paper presents various observations, from electromagnetic simulations, of a metamaterial embedded patch antenna. The composite right left handed (CRLH) transmission line (TL) metamaterial is the metamaterial under consideration. The schematic structure of the CRLH TL embedded in a patch antenna is shown. This structure is supported on a substrate of thickness 1.59 mm and dielectric constant 2.4. Compared to a simple probe fed patch antenna there is an improvement for the metamaterial embedded patch. Simulations have been done by inserting a single and a double metamaterial structure in the patch antenna. There is an increase in gain, antenna efficiency, shift in resonant frequency and dual frequency of operation for the embedded metamaterial patch.
