Design and analysis with different substrate materials of a new metamaterial for satellite applications

Abstract

Abstract In this paper, we are presenting a new metamaterial unit cell for satellite applications. The unit cell of the metamaterial was designed on FR-4 substrate material. The transmission characteristics of the unit cell display resonance at the frequency of 3.45 GHz of S-band of microwave region, which is usually suited for satellite communications. We did further analysis on the material’s effective medium properties by replacing the substrate material with Rogers RT 6010, lossy polyimide and aluminum nitride substrate materials, and we achieved different promising electromagnetic properties including double negative characteristics within the same band as well. For all these analyses, the popular “CST Microwave Studio” simulation software was adopted. The proposed design gives fine controllability in different types of metamaterial just by changing the substrate material, and all are working in the same S-band microwave spectrum.
