Abstract

Overview

This article investigates the feasibility of using pure aluminum for electromagnetic shielding in the 5G frequency region. It addresses the need for effective shielding solutions against potential health effects due to the proliferation of 5G technologies.

Findings

The study analyzes the shielding effectiveness (SE) of pure aluminum at various thicknesses and frequencies using experimental method. Key points include:

• Aluminum demonstrates increased shielding effectiveness in the 5G frequency range as the material's thickness increases.
• Aluminum sheets, when designed differently, show varied electromagnetic shielding efficiencies.
• The effectiveness is particularly notable in the 4.5 and 5.1 GHz frequency ranges.
• Experimental data reveal that aluminum's absorption characteristic in the sub-6 GHz range for 5G is more predominant than its reflection characteristic.

Conclusion

The paper concludes that pure aluminum is a viable and cost-effective material for electromagnetic shielding in 5G applications. The potential of aluminum as a shielding material is emphasized, based on the significant SE observed and its physical and commercial benefits.
