This paper presents the analysis and optimization of a PIFA antenna radiation performance in the presence of the user. The antenna covers GSM-900 (0.86-0.96 GHz) and DCS-1800 (1.71-1.8 GHz). The user is quantified and interprets with a Specific Anthropomorphic Mannequin (SAM). We used the method of adaptation. Indeed, we used an LC resonator placed between the power supply and radiating patch to ensure adaptation (to maximize gain).The simulation results show a good compromise between the factors in the design of mobile phone antennas. The parameters considered in this work are the resonant frequency, return loss, bandwidth, radiation pattern, gain and the specific absorption rate (SAR). All simulation results were made by the CST Microwave Studio.
