| Abstract: | The characteristics of the specific absorption rate(SAR)distributions calculated by the finite difference time domain(FDTD)method using a homogeneity head model and a hand held portable radio model was presented.The SAR distribution around the monopole antenna and the head model was analyzed and a proposal of effective way was studied.Furthermore,this paper checked how antennas near field is affected by the dielectric block. |
