Abstract

This article presents a 12-element multiple-input multiple-output (MIMO) antenna system for fifth-generation mobile phones. To improve isolation, split-ring resonators are positioned adjacent to the radiating elements in the proposed design, which features a flower-shaped antenna radiator etched along the side frames of the device. The antenna system provides an isolation of over 15 dB between the elements with a wide operational band of 3.0-7.5 GHz. Simulations and experiments demonstrate that sublime presentations have an overall efficiency of 58%-78% across the operational band and an ECC of less than 0.05. Additionally, the impact of user's hand grip, plastic frame, and battery integration is analyzed. The robustness of the proposed design was confirmed by the alignment between the simulated and measured results.
