Review Paper on Metamaterial based Superstrate Antenna

Abstract

The aim in this paper is to review a new form of micro strip Patch antenna with metamaterial based superstrate inspired by an ordinary patch antenna resonating for various applications. It is shown that by implementing innovative resonators structure into the design, there is simultaneous gain and bandwidth improvement. The results in terms of gain, bandwidth, radiation pattern and return loss are analyzed in detail, which allows us to develop a comparative study according to the  distance separating the superstrate placed in the antenna. In recent decade with the use of metamaterial based superstrate the size of antenna have been drastically reduce to very small sizes and light weight for actual practical application.
