Simulation Of Cell Phone Antennas On The Human Head Electromagnetic Radiation

With the rapid development of modern communication technology and the continuous improvementof people’s living standard，The use of mobile phones more and more popular。Mobile phones havebecome our each person’s indispensable tool of communication and entertainment. Due to the mobilephones when it is working antenna near the people head, the induction and radiation produced byMobile phone near field can produce certain harm to the head, so the question of phone radiation hasbeen long the focus of the research.This paper cites the classic electromagnetism calculation method-the Finite Integral Method tocalculate the Specific Absorption Rate of the head when the antenna radiation.This paper is divided into five chapters, the first chapter mainly introduces the definition of SAR,safety and health standards and research situation at home and abroad.In the second chapter, we particularly introduce the basic principle and important content ofFinite Integral MethodIn the third chapter, we particularly introduce the basic principle and design method of the PlanarInverted F antenna.In the fourth chapter we use CST software based on FIT algorithm to structure PIFA antennaand human head model,and Analyzed PIFA antenna when it is working in the frequency of900MHZ and1800MHZ the SAR distribution in the human body head. And we talk about the SARdistribution in cases of earrings and the ring teeth. The analysis results show that the distribution ofhuman head SAR is uneven, when earrings with human head the SAR would be decreased.Conclusions and outlook are given in chapter5．...
