Abstract

Overview

Understanding compliance with electromagnetic field (EMF) exposure limits for user equipment (UE) is crucial. These limits affect how power is transmitted and managed in telecommunications devices, especially with the adoption of 5G technology.

Findings

This study assesses the implications of revised incident power density limits for 5G millimeter-wave user equipment. It involves:

  • Numerical modeling of patch antenna arrays with varying sizes.
  • Analysis considering beam-steering operations at frequencies between 10 GHz and 100 GHz.
  • Comparison with the 3rd Generation Partnership Project (3GPP) guidelines on total and isotropic radiated power levels.

International guidelines like those from the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the IEEE have recently been updated, which this research takes into account. Similar protocols by the US Federal Communications Commission (FCC) are also considered.

Conclusion

The study provides critical insights that can aid equipment manufacturers, network operators, and standardization bodies in meeting updated RF EMF exposure guidelines and understanding their health implications better.
