In this paper, a new wideband metamaterial truncated structure unit cell is introduced,
comprising a novel unit cell design aimed at enhancing 5G applications. The unit cell features a truncated
structure with a decagon ring slotted in a patch with three slits and is designed on a low-cost FR-4 lossy
substrate. With dimensions of 13.8×13.8 mm² and a thickness of 1.6 mm (εr = 4.4, tanδ = 0.02), the
proposed metamaterial unit cell covers a wideband frequency range from 7.5 GHz to 9.2 GHz. Notably, it
spans segments of the S-band and extends into the C-band within the microwave regime. Simulation results
highlight the unit cell's intriguing performance features, particularly its wideband capabilities. These
characteristics position the proposed metamaterial unit cell as a promising solution for enhancing Multiple
Input Multiple Output (MIMO) performance in 5G communication systems. Through comprehensive
analysis, this study underscores the potential of the proposed metamaterial design to address the evolving
demands of high-speed data transmission and reliable connectivity in modern wireless communication
networks.
