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

Abstract

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 mm2, 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 (S21) 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.
