Metamaterials (MTM) have started to play an indispensable role in innovative devices. The characteristics laid out by these materials are exceptional, not found in natural materials. This paper analyses the historical expansion in the field of MTM and studies two universally useful Split Ring Resonators: Circular SRR (C-SRR) and Squared SRR (S-SRR) with reference to the Kramers–Kronig accord at sub-6 GHz frequency. Reflection coefficient (S11) and transmission coefficient (S21) are observed with an electromagnetic solver and further with the help of MATLAB. The electric permittivity and magnetic permeability outcome indicate that the condition for metamaterial structures has been satisfied. Their characteristics are compared for 5G C-band frequency domain. Also, both the structures have been manually fabricated. The proposed structures embedded in electronic circuitry will aid in size miniaturization, to benefit the researchers in the field of communication, medicine and military.
