Abstract :
In this study, we constructed the realistic model of flip phone and calculated the reflection coefficient of the antenna. As the results, the operating frequencies of the antenna agree with the targeted value (900 MHz, 2GHz). In addition, we made the comparison of the SAR distributions in a simple phantom model for a flip phone model and PIFA. From the result, we confirmed the SAR distributions of PIFA are wider than that of high resolution model and SAR values of PIFA are higher than that of high resolution model. To calculate more accurately, it is necessary to construct higher resolution model. In the future, the high resolution human model and other devices will be studied.
