Factors Influencing the EM Interaction between Mobile Phone Antennas and Human Head

This paper presents a procedure for the evaluation of the Electromagnetic (EM) interaction between the mobile phone antenna and human head, and investigates the factors may influence this interaction. These factors are considered for different mobile phone handset models operating in the GSM900, GSM1800/DCS, and UMTS/IMT-2000 bands, and next to head in cheek and tilt positions, in compliance with IEEE-standard 1528. Homogeneous and heterogeneous CAD-models were used to simulate the mobile phone user’s head. A validation of our EM interaction computation using both Yee-FDTD and ADI-FDTD was achieved by comparison with previously published works.
