Simulating the Dispersion of the Energy Flux Density of the Electromagnetic Field Generated by Antennas for Mobile Communications

Abstract

Overview

The recent two decades have seen a significant increase in the number of telecommunication antennas located in residential areas, which emit electromagnetic radiation. This study focuses on simulating the dispersion of the electromagnetic fields generated by these antennas.

Findings

• The simulation used the AutoCad software to visually represent the spread of electromagnetic radiation based on physical wave properties.
• Comparative analysis of the simulated and measured energy flux densities indicates a 30% overlap.
• At distances less than 30 meters from antennas, notable electromagnetic radiation levels of 10 to 10,000 µW/cm2 were observed, potentially exceeding the FCC's exposure limits.
• Beyond 30 meters, the radiation levels significantly decrease and fluctuate between 10 to 0.001 µW/cm2, and further at distances beyond 100 meters, the levels are from 0.01 to 1 µW/cm2 in free space.

Conclusion

The simulations reveal that close proximity to mobile telecommunications antennas can result in significantly high levels of electromagnetic radiation, suggesting the need for further experimental checks to confirm safety compliance, especially in uneven terrains. Effective simulation can aid in understanding and managing electromagnetic radiation from antennas, highlighting areas where radiation exceeds safe limits.
