Research Abstract

In our study, we have investigated the frequency dependence of communication channels for the body area networks in a frequency range from 3 MHz to 3 GHz by employing numerical simulations. As a result, it was clarified that the dependence of the received voltage on the posture is relatively small in a frequency range below 100 MHz. In addition, it was found that there are discrete frequency points in which the posture dependence of the received voltage is significant. Furthermore, we have investigated an equivalent circuit of the communication channels for the frequency range below several megahertz. As a result, it was clarified that the capacitances between transmitting and receiving antennas are not negligible and so the posture variation may have to be considered even in the low frequency range.
