With the current expansion and the anticipated further increase in the use of cellular telephones and other wireless communication devices, considerable research effort is devoted to investigations of interactions between antennas on handsets and the human body. This interaction significantly changes the antenna characteristics from that in free space or even on the device (handset, laptop). In this paper and in order to study this problem, firstly a planar inverted-F antenna (PIFA) was designed and simulated to operate over the frequency 2,45 GHz , then the influence of the human head on the return loss and on the radiation efficiency of the antenna has been studied.
