Metamaterial for Antenna Performance Enhancement: A Review

Antennas are one of the most essential components of any wireless communication system. As wireless communication has advanced, the same development has been seen in antenna designs as well. The requirement for large bandwidth, high gain, multi-band antenna, and miniaturization of antenna size is increased. Metamaterials can be used to increase the performance of antennas either by enhancing parameters such as bandwidth or power gain or by creating compact, multi-frequency band antennas. This paper presents the review of the antenna performance enhancement by incorporating metamate-rials in different ways into antenna design.
