A Survey on applications of Metamaterials in Antenna Design

Recent advancements in telecommunication sector focuses on developing miniaturized devices with the integration of multiple functions as per the customers need. Mobile systems, smart portable equipment, communication receivers, wireless networks require antennas which are compact and condensed in size, one that possesses good gain and has multiband functionalities. To enhance these antenna parameters novel artificial materials are known as metamaterials are incorporated in antenna designs. Broad classification of metamaterials is presented in this paper with emphasis on their functionality in antenna design. Applications of such artificial structures in enhancing antenna gain, in miniaturization of antenna size, to get multi-band characteristics are discussed extensively. A comparative survey is presented to highlight the advantages of using the metamaterial antennas as against the conventional antennas to the above-mentioned parameters. The purpose of this paper is to analyze the best structure for specific applications and testify the significant improvements obtained because of the meta structures.
