Abstract

Abstract Summary: Electromagnetic Exposure from Wearable Antennas

Overview

This study evaluates human exposure to electromagnetic fields (EMF) generated by wearable antennas operating at 5G frequencies. Emphasis is placed on understanding the potential risks associated with these devices as their use becomes more prevalent.

Methods

• Frequency Use: Two antennas were assessed, one at a lower 5G frequency (3.5 GHz) and another at a higher frequency (26.5 GHz).
• Simulation: Electromagnetic simulations were performed using four human models to measure exposure.
• Metrics Assessed: Specific absorption rate (SAR10g) and absorbed power density (Sab) were the parameters measured.

Findings

The highest exposures were noted directly beneath the antenna locations on the trunk of the human models, with a decrease in exposure levels at further distances. Despite these high local exposure levels, all measured values were within the safe limits established by ICNIRP guidelines, assuming realistic input power scenarios.

Conclusion

This investigation underscores the necessity of rigorous exposure assessments, particularly in light of the expanding use of wearable technologies in various applications, including future 5G networks.
