G Loaded Complementary Split Square Ring Resonator-Based SNG Metamaterial for Wi-Fi, IoT & Satellite Applications

In this study, a novel miniaturized G-inspired complementary split square ring resonator-based single negative (SNG) metamaterial (MTM) has been developed for wireless fidelity (Wi-Fi), internet of thing (IoT), and Satellite applications. Commercially available user-friendly computer simulation technology (CST-2019) electromagnetic simulator was used for the layout design and detailed analysis of the produced structure. The MTM unit cell size is 8×8 mm
²
, and it is integrated on a Rogers RO4350B dielectric substrate. A high effective medium ratio (EMR) is obtained from this structure; the value of it is 15.63. The effective medium parameters were extracted using the Nicolson-Ross-Weir (NRW) approach. To design the recommended MTM, various parametric studies have been done. Over a wide frequency range, the constructed structure has negative permittivity and also the negative refractive index. The obtained transmission coefficient (S
21
) resonance frequencies are 2.40, 4.18, 6.57, and 10.36 GHz, which covers S-, C-, and X- bands. Since the size of the designed cell is small, high EMR, desired resonance frequency, and the maximum band have been found; hence it can be used in Wi-Fi, IoT, and satellite applications.
