Abstract

In this paper, the specific absorption rate (SAR) and the temperature rise in the SAM phantom human head model as a consequence of the exposure to radiation of planar inverted F (PIFA) mobile handset antenna has been estimated at Advanced Wireless Services (AWS) band downlink frequency range. Biological hazards on human head owing to electromagnetic wave (EMW) exposure in advanced wireless services has been analyzed by computing the temperature rise in head's tissue. A miniaturized planar inverted F antenna having dimension of 15.9×10×4  is located aside human head using COMSOL Multiphysics 5.0 to establish a pragmatic analysis. Even a source data created from magnetic-resonance image (MRI) of a human head is imported for estimating the variation of tissue type inside head. In this model, Radio Frequency (RF) Module and Heat Transfer Module have been elected for accurate analysis of the physical element, i.e., planar inverted F antenna and the biological element, i.e., human head correspondingly
