The circularly bent split ring resonator with a high effective medium ratio for multi frequency satellite band applications

The scattering parameter for the interaction with the electromagnetic wave is introduced the interesting properties of the effective parameter. The compactness of the subwavelength based metal-dielectric based resonator is related to the tailored metallic design. In this research work, two circular bent split ring resonator is represented with four resonant frequencies for S, C band applications. This subwavelength based metamaterial resonator exhibit the bandwidth from 1.97 to 2.11, 3.43–3.63, 5.31–5.46, 8.3–8.6 GHz at 2.03, 3.57, 5.37, 8.47 GHz, respectively. The geometric specification, equivalent circuit model, design selection process are included to observe the electromagnetic characteristics, and the electric field, magnetic field and surface current distribution are used to analyse the state of polarisation at different resonant frequencies for the applied transverse electromagnetic wave. In parametric analysis, the relative angular rotation of two bent circular split resonators expresses the effect of the metallic layer with the rearrangement of the gap between the conducting layers. Moreover, different substrate materials with a change in thickness are analysed to characterize the scattering properties for different dielectric constants.
