✦ Synopsis

With the rapid proliferation of cellular telephones, there is concern regarding the detrimental effect of the electromagnetic waves on the human body. As a method to reduce the absorbed power (SAR) in the human body, a cellular phone with two antennas is proposed. As the simplest model, two line current sources placed on the two-dimensional cylindrical human head and its neighborhood are considered. The structure is compared with a single line current source on the human head. From the numerical results, it is shown that the total absorbed power can be reduced by 10% and the peak SAR to one-quarter.
