Abstract

Overview

With the advancements in 5th generation (5G) mobile networks and increasing exposure to the upper parts of the microwave spectrum, concerns regarding electromagnetic fields and their health impacts have escalated. This study uniquely explores how age and clothing can modify power absorption in the human body under specific 5G network frequencies.

Findings

• The investigation utilized an array of four Yagi antennas operating at 26 GHz and 60 GHz to simulate near-field exposure conditions.
• Age-related effects showed varied absorption rates: the maximum increase was observed in 70-year-olds, while the largest decrease was noted in 5-year-old children.
• Textile presence can alter absorption rates significantly depending on several factors like the material's thickness and permittivity, and the air gap between the textile and skin.
• When cotton and wool were tested, they showed an increase in absorbed power density by approximately 40% compared to bare skin.

Conclusion

This study underscores the need for comprehensive policies and protective measures for vulnerable populations, particularly children, regarding electromagnetic exposure in emerging technological environments like 5G.
