Biometric System: Study of Radiation on the Human Arm
Article Sidebar
Main Article Content
Abstract
The study assessed radiation power absorption in the 1.5 to 5 GHz range for Wi-Fi, LTE, and AM modulation, using three Vivaldi antennas in an anechoic chamber with a phantom arm made of animal bone, ballistic gel, and pigskin. Wi-Fi showed the highest absorption levels, but these values (0.168 mW and 0.050 mW) were below ICNIRP safety limits, indicating no significant risk to human health.
