Abstract:

In this review paper, distinctive properties of metamaterial, prominently negative refractive index materials are presented. Metamaterials are macroscopic composites that have three dimensional periodic structures which are artificial (man-made) for an optimized combination, not readily accessible in nature. Metamaterial shows unexpected properties such as negative permittivity and negative permeability simultaneously that leads to negative refractive index which supports backward waves. Metamaterial in antennas are used to enhance dual-band and multi-band characteristics along with antenna size reduction, increase in bandwidth and radiator efficiency. They are classifying into a variety of category such as antenna based on metaresonators, metasurfaces, and metamaterial loadings. The main aim of the research work is to deal with topic in broad way, and to review the state of art progress in the field of metamaterial-inspired antennas.
