Abstract :
This paper analyzes the specific absorption rate (SAR) induced in human head model of various sizes by a mobile phone at 900 and 1800 MHz. Specifically the study is considering in SAR between adults and children. Moreover, these differences are assessed for compliance with international safety guidelines. Also the effects of these head models on the most important terms for a mobile terminal antenna designer, namely: radiation efficiency, total efficiency and directivity, are investigated.
