In this research paper, we present a comprehensive analysis of metamaterial unit cells for antenna engineering. The analysis includes the examination of unit cells with both single and double substrates through a waveguide medium. The first unit cell comprises a split ring resonator (SRR) with two splits placed within the perpendicular sides. Inside the SRR, a circular splitted ring resonator (C-SRR) is printed on a copper-backed FR4 dielectric substrate. This configuration exhibits a stop-band phenomenon at 5.5 GHz. The second unit cell also consists of an SRR with two splits within the perpendicular sides. Inside this structure, a circular splitted ring resonator (C-SRR) is designed using two different substrates (FR4 and Rogers RT5880) backed by a metallic ground plane. This unit cell demonstrates a stop-band phenomenon at 10.7 GHz. Furthermore, we conduct a detailed analysis of the extraction of medium parameters such as permittivity and permeability for both metamaterial unit cells. The extraction methodology and results are discussed extensively. To validate our findings, simulations are performed using the CST Microwave Studio, a widely-used commercial software in the field. Through these simulations, we obtain reliable and significant results.
