“…More and more people want to know whether any confirmed effects have been stated yet [8] and how to overcome the matter without stopping the usage [9][10][11][12][13], resulting in on-going research for decades to analyze the rate of electromagnetic wave being absorbed into a specific averaged mass of tissue of a human body [9,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] and even animals [34][35][36]. The value is obtained by measuring the time rate of RF energy absorption which is given in terms of specific absorption rate (SAR) at various part of body, for example head and hand in the case of mobile phone [20,22,23,25,26,[28][29][30][31][32][33]. SAR can be defined as:…”

Abstract-A simple geometrical Asian-hand model with human tissue properties posed at two common talk-mode positions is proposed for comparative study. The newly designed hand is formed by measuring an adult female hand at open-hand position before being posed into the presented styles. Four human hand tissues are included: skin, bone, muscle, and tendon, and also three homogeneous sets of hands using specific anthropomorphic mannequin (SAM) hand phantom dielectric properties. A candy-bar type mobile phone with Planar Inverted-F Antenna (PIFA) is used to radiate dual-band frequency of GSM900/1800 in the vicinity of the SAM head phantom. The mobile phone casing is made out of plastic, and only two components are considered: the FR-4 ground plane and PIFA. The specific absorption rate (SAR) averaged over a mass of 10 gram and 1 gram is calculated after obtaining the power loss density and electric field value from simulation in CST Studio Suite 2011. The SAR and return loss results of six hand structures, including the SAM hand phantom are compared. The antenna performance with the inclusion of hand does not decrease as much as 1800 MHz in 900 MHz range, but absorbs energy more in the hands for 1800 MHz than 900 MHz SAR values.
