Abstract

The electromagnetic exposure from mobile phones has attracted the attention of many researchers. In this paper, we established four kinds of mobile phone simulation models according to the different antennas and phone shells. These models also include the mobile phone components of protective glass, conductive glass, screen back plate, battery, and PCB dielectric slab. We studied the effect of the shell material on the specific absorption rate (SAR) of energy deposition in the body, such as plastic and metal shells. We compared the exposure levels of the mobile phone with the planar inverted-F antenna (PIFA) and the planar monopole antenna (PMA). We analyzed the SAR distribution when a person is in sitting or standing postures, or holds the top, middle and bottom of the mobile phone.
