Analysis of a novel designed bowtie shaped DNG metamaterial for satellite applications

Abstract

In this paper, a new double negative metamaterial unit cell structure with low profile of 6.5×6.5 m2 is proposed. The unit cell shows Double NeGative (DNG) characteristics in S-Band and Epsilon NeGative (ENG) in C-Band frequency. The characteristics of the proposed unit cell are studied with the popular FR-4 substrate and also with the Rogers RT6010 substrate that exhibits a higher dielectric constant. A comparison of the unit cell characteristics in 1×2, 2×2 and 3×3 array structures is made, to validate the performance of the split ring resonators (SRR) as a metamaterial. The reflection and transmission parameters of the unit cell are obtained using commercially available package CST software; then the EM properties are extracted using the smiths’ method. The proposed unit named bowtie cell can find potential use in satellite communication systems.
