This paper presents an investigation of the effect of the internal antenna on the specific absorption rate (SAR), and the effect of the presence of a human head at close proximity to a mobile phone upon the antenna performance in mobile‐phone applications. Both the experimental measurement and numerical simulation of the SAR values and the antenna performance parameters of a typical internal antenna are presented. The results indicate that the far‐field radiations of the internal antenna can be reduced by 3 dB with the presence of human head. © 2005 Wiley Periodicals, Inc.
