Design and PCR calculation of Triangular Ring Resonator (TRR) metamaterial for wide range of applications

In the proposed work, triangular ring resonator (TRR) is designed and PCR calculation of TRR metamaterial is studied with the help of the design of split ring resonator (SRR) metamaterial. TRR is designed on FR-4 substrate of permittivity 4.3. This structure is numerically analyzed using commercial software CST studio tool for two turns only. In this work, the equations derived for resonant frequency are simplified for evaluating effective dielectric constant of the substrate after incorporation of metallic base. Obtained frequency for its reflection coefficient is 12.4 GHz. Polarization conversion ratio (PCR) has been plotted against the frequency.
