The antenna design is based on conventional structure with flexible substrate features and copper as the conductive plane. The simulation analysis was performed in CST Microwave Studio. Anatomic simulation using HUGO voxel model was used for on-body simulation and electromagnetic dosimetry. For off-body analysis, the antenna resonates at 2.45 GHz with S11 parameter of -32.56 dB and radiates unidirectionally with efficiency of 91.96 %. It was found that the presence of human lossy tissues and organs caused frequency detuning of 50.4-51.5 MHz and radiation efficiency degradation of 7.93 % to 13.78 %. The electromagnetic dosimetry on specific absorption rate (SAR) exposure of the antenna when it is mounted over averaged 10 g of tissues for chest, back, abdomen, arm and thigh was well below the IEEE Std. C95.3 limit. The maximum and minimum SAR was found when the antenna was placed on the back (0.332 W/kg) and arm (0.121 W/kg) respectively on the human body. Varying the distance from 0-20 mm of the antenna from the human body reduces the SAR exposure to the human body.}, number={1-4}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Yew, B.S. and Wee, F.H. and Bahri, S. and Muhamad, M.}, year={2017}, month={Mar.}, pages={37–40} }
