Study How the Hand Affects on the Mobile Phone Dipole Antenna Matching Conditions to the Free Space at 3700 MHz Frequency

The purpose of the presented study is to investigate EM exposure on realistic inhomogeneous human models to test mobile phones in terms of electromagnetic (EM) safety. The influence of the human hand (fingers positions) during communication on the mobile phones' antenna matching conditions was studied through computer modeling using the Finite-Difference Time-Domain (FDTD) method for the 3700 MHz communication frequency. Dielectric heating effects caused by EMF absorption in human tissues have been considered in this paper.
