Abstract

Overview

This study aims to investigate human exposure to electromagnetic fields (EMF) generated by wearable antennas designed for 5G technologies. The focus is to determine how these emissions interact with the human body.

Methods Employed

• Two types of wearable antennas were tested, tuned to lower and upper bands of 5G frequencies.
• The antennas were placed on the trunk area of simulated human models.
• Electromagnetic numerical simulations were utilized to measure exposure.
• Metrics used included the specific absorption rate (SAR10g) and absorbed power density (Sab).

Findings

The results showed that higher EMF exposure values were localized below the antenna and reduced in intensity further from the antenna position. Despite higher localized exposure, all assessed levels were within international safety guidelines (ICNIRP).

Conclusion

The study underscores the critical importance of evaluating EMF exposure, especially as wearable technology in 5G networks expands. It also confirms that current safety limits offer protection against elevated levels of EMF exposure.
