The 5G mobile communication systems are the “next generation” communication systems. They are capable of providing numerous benefits to the mobile phone users. But, whether they are safe to use is still a topic of concern. This study investigates the thermal safety of 5G mobile phone frequency. A three dimensional multi-layered skin tissue is exposed to 60 GHz frequency from a mobile patch antenna. The simulation software COMSOL Multiphysics is employed to map the electric field distribution and the temperature distribution within the exposed domain. The peak temperature (37.36°C) is estimated in the subcutaneous fat layer of the skin tissue. The temperature peak is very short lived and the steady state temperature is same as the core body temperature. The results suggest that the temperature rise caused by the 5G mobile phone radiation exposure is not capable of causing the thermal burns in the exposed tissue. Therefore, the 5G mobile communication frequency of 60 GHz can be considered “thermally” safe.
