Investigation of SAR exposure assessment in vital human tissues at GSM frequency

Abstract

The human exposure assessment is dependent on the measurement parameter such as Specific Absorption Rate (SAR). SAR investigation highlights the biological impact of human health due to a radiation source. This paper proposes a novel investigatory method for SAR assessment on human tissues such as kidney, heart, lungs, trachea, and nerve. The radiation source is considered is Inverted F Antenna designed to operate at GSM frequency 900 MHz. The tissue structures are designed with equivalent properties. The experimental analysis of exposure on tissues is performed, and SAR is computed. The various response of tissues towards SAR is compared and analyzed with gain and operation characteristics.
