Measurement and Evaluation of the EM Field Impact in the Range of 4G/5G Frequencies

The aim of paper is to extract the spectral frequency radiation in the range of 4G operations. The experimental setup, supplemented by spectrum analyzer USB-SA44B supplemented by the respective software, notebook for analysis of signals, transmitting-receiving antenna array consisting of four microstrip antennas, the transmitting antenna operating in the frequencies 0.9 GHz, 1.8 GHz and 2.45 GHz, and signal generator SA6 is used for the measurements. The designed setup demonstrates the possibility to extract the spectral characteristics of radiation in the range of 4G operations. It is observed that the fixed strength of radiation depends on the sources of radiation. The perspective of design is evaluation of the SAR at the laboratory environment.
