Abstract :
In this paper we suppose to discuss recent results of study influence of Electromagnetic (EM) exposure of mobile phones radiation on a human. After calculations on different existed standard frequencies, with different distances between user´s head and antenna using different antenna types were conducted (all calculation are part of ongoing MMFPII research project according to the specified) it appeared that there is more information needed for analyses of thermal response than just calculating peak values of Spatial Absorption Rate (SAR) and temperature rise to be studied. In it was shown, that presence and position of the hand (which is actually required in order to use the phone) substantially can change users head exposure and radiation pattern. In this paper it is shown, that during analysis exposure we could consider another parameters of the antenna´s position.
