Abstract

Recently, metamaterial has grabbed prime focus of research fraternity working in the field of antennas, microwave filters and components design. Many different structures of split ring resonators (SRR) for their respective applications have been reported till date. In all of these findings in some way or other, using metamaterial, drastic reduction in size of the component has been achieved. Thus, the metamaterial can be viewed as a powerful miniaturization tool in the field of radio frequency (RF) and microwave. Since its inception in 1999, many variants of SRR have come up leading to more efficient designs with better RF properties. This review paper presents an application based review of such variants and will be useful for new researchers exploring its use in their research problems.

Key words: Metamaterial, antenna miniaturization, negative refractive index metamaterial (NRIM),split ring resonators (SRR).
