Abstract

Overview

This study presents the development of an in vitro experimental system specifically designed for investigating the effects of fifth-generation (5G) electromagnetic fields at 3.5 GHz. A unique setting within an incubator supports accurate 5G exposures using sophisticated equipment.

Experimental Setup

• A radial transmission line (RTL) supports single-mode propagation at the required frequency.
• A conical antenna centered in the RTL ensures the symmetry of the field.
• The system employs a 5G signal generator and a customized power amplifier for generating 5G new radio time division duplex (TDD) waveforms.
• A feedback mechanism utilizing a directional coupler and power meter facilitates precise power control.

Findings

The integrity of the system was verified through temperature measurements and nonlinear curve fitting to determine specific absorption rate (SAR) values. Initial results comparing SAR from maximum power and actual 5G TDD transmissions confirm the system's efficacy, showing similar ratios as theoretical expectations.

Conclusion

The experimental system effectively replicates 5G signals and ensures controlled environmental conditions, making it a valuable tool for further in vitro research on the potential health impacts of 5G radiation exposure.
