“…Authors in [10] combined metamaterial configurations positioned between single-band (PIFA) and the human head and the SAR is condensed by 53% for 1 g tissue mass. In [11], the reduction of SAR is done by leading a U-edge wall made of an engrossing water material at each corner of the ground plane. In [12], the mobile antenna is intended to decrease antenna radiation towards the human body using the vertical sidewalls to blockade the radiation to the human body.…”

Aims: The objective of this paper is to design a new PIFA for cell phone applications with low SAR. Study Design: The designed PIFA antenna involves a patch with slots on the upper side of first substance layer FR-4, shorting wall, and a ground plane in the bottom side of second substance layer FR-4 and exciting (feeding port). Place and Duration of Study: Department of Electronics and Communication Engineering, Faculty of Engineering, University of Zagazig. Between December 2017 to March 2019. Methodology: it will be utilized SAM head model and a hand phantom as a user’s head and hand. Time-domain solver considers hexahedral mesh with adaptive meshing scheme used in this simulation. Results: The simulation result has been obtained using MWS CST tools which constructed on the finite integration technique. And the measurement results are accomplished with vector analyzer ZVA 67. The simulated and the investigational results are the same approximately. Conclusion: The antenna provides high gain for both frequency bands (900MHZ and 1800MHZ) with approximately 90% radiation efficiency. Moreover, The SAR analysis of the suggested antenna clearly demonstrates little SAR characteristics suitable for human usage competed with the standards of the safe SAR values.
