Crossed metal SRR metamaterial with high impact factor for satellite frequency applications

The authors of this study were prompted by the size and resonance behaviour constraints of the existing conventional metamaterial for satellite frequency applications to build and explore a unique metamaterial design with a split-ring resonator (SRR) structure. The proposed split-ring resonator metamaterial with intersecting metal was constructed using Computer Simulation Technique (CST) Studio Suite software. The compact SRR with the dimension 10 × 10 mm² was developed on an FR-4 substrate material and analytically simulated using the frequency domain technique by setting a frequency range from 0 to 18 GHz. The suggested SRR generated sextuple-band resonance frequencies of 3.20 (S-band), 6.05, 7.97 (C-band), 9.47 (X-band), 14.72, and 16.78 (Ku-band). The resonance frequencies exhibited both single- and double-negative features. Meanwhile, the effective medium ratio (EMR) value of the proposed SRR metamaterial is 9.38. The described SRR metamaterial is highly suited for microwave frequency applications, notably those employed in satellite communication, because of its narrow and sextuple-band responses.
