Many researchers are exploring the dielectric properties of the human body considering the increasing prevalence of mobile phone infrastructure. Using a cell phone for a long time may increase the risk of getting abnormality of human parts because the RFEME (radio frequency electromagnetic energy) emits electromagnetic radiation energy on humans. In the cell phone communications, a microstrip patch inside of the phone transmits electromagnetic radiation. As a result of mobile phone antenna radiation, human beings are exposed to electromagnetic field radiation every day. It is difficult to determine the long-term impact of radiation on the human body, because of the complexity of human anatomy. Several important variables are taken into consideration while evaluating the impact of antennas' radiation based on human body parts such as its permittivity, conductivity, depth of penetration, and specific absorption rates are being calculated using the available human’s properties, the temperature of selected human’s parts calculated using Penne’s bioheat equation. As is demonstrated in this purpose, we investigate the careful evaluation of the fundamental equation of relative permittivity, conductivity, specific absorption rate (SAR), and penetration depth (PD) also known as skin depth considering the widely available application of cell phones in GSM-phone innovation in 3G, 4G and 5G communications. To create the model, MATLAB is used for theoretical calculations for selected humans’ tissues.
