Abstract

Overview

For the first time, we present a design of a millimeter-wave personal exposure meter (mm-PEM) aimed at assessing exposure to the 5th generation of mobile networks (5G) in indoor diffuse fields. The meter is crucial for understanding the potential health risks associated with 5G exposure.

Findings

• The mm-PEM has been designed using simulations and on-phantom calibration measurements in a 60 GHz mm-wave reverberation chamber.
• It features an array of nine antennas on the body, measuring the incident power density (IPD) and ensuring minimal measurement uncertainty.
• The study achieved a key response figure of 1.043 at 60 GHz, which closely approximates the ideal response, signifying accuracy in real-world conditions.
• Average absorption cross-section of the phantom was found to be in excellent agreement with its physical dimensions, further validating the design's effectiveness.

Conclusion

The designed mm-PEM is calibrated accurately for use in diffuse indoor environments that reflect real-world scenarios where 5G technology is utilized. This emphasizes its capability to effectively measure 5G exposure, which is critical for evaluating potential health risks.

Recommendations for Future Research

Future research should focus on improving the design of acquisition nodes and calibration procedures to enhance measurement accuracy and reliability in varied environments, reflecting realistic human body influences.
