Analysis of the Electric Field Strength Emitted by Wireless Devices Operating at 868.3 MHz in the Vicinity of the Human Body

The aim of this article is to investigate the impact of the electric field emitted by an antenna operating at a frequency of 868.3 MHz on the human body. The operating frequency falls within the radiofrequency range and was chosen due to its widespread use in various wireless communication systems, such as smart building and security systems. This simulation was conducted using the COMSOL Multiphysics software and was performed in the Radio Frequency, Electromagnetic Waves, Frequency Domain (EMW). The elements that compose this simulation are: the human body, the signal-emitting antenna and the enclosure. Within the simulation, it has been observed that the equipment operating at the 868.3 MHz frequency emits a low electric field strength near the human body, that has a non-hazardous impact under safe conditions.
