Abstract

This paper focuses on the interaction between two types of antenna (Slot Coupled Patch Antenna and Probe Feed Patch Antenna) and human head model at 835MHz. Real experiments on human body and electromagnetic fields is not possible because of it the HFSS software has been used to simulate the head model and antenna as an exposure source. The simulation results (calculated in SAR and E field strength parameters) show that the electromagnetic fields can be absorbed in human tissues. Regular papers have been done in this way. In this paper it is shown that the human tissues can decrease the gain of antenna as an interaction.
