Assessment Procedure of the EM Interaction between Mobile Phone Antennae and Human Body

This paper presents a procedure for the evaluation of the Electromagnetic (EM) interaction between the mobile phone antenna and human body, i.e., head and hand, and investigates the factors may influence this interaction. These factors are considered for different mobile phone handset models, different form factors and different antenna types, operating in the GSM900, GSM1800/DCS, and UMTS/IMT- 2000 bands. A realistic usage of mobile phone handset next to head at cheek and tilt positions, in compliance with IEEE-standard 152, is considered during computations. Homogeneous and heterogeneous CADmodels are used to simulate the mobile phone user’s head, whereas, a homogeneous model with three different tissues is designed to simulate the user's hand-hold. A validation of our EM interaction computation using both Yee-FDTD and ADI-FDTD is achieved by comparison with previously published works.
