Consideration for Polarization of Antennas in Dynamic Body Area Networks at 400 MHz narrow band.

This paper presents a consideration for directions of both transmitting and receiving antennas in dynamic on-body networks at 403.5 MHz by using FDTD simulation results. The temporal level difference for the six human movements and the six receiving locations are calculated with the antenna directions u, v, and w. The statistical analysis shows that the overall level variations are well modeled by the lognormal fittings by individual combinations of the transmitting and the receiving antenna directions. It is shown that the UW combination of the antenna direction gives largest received level with smallest deviation, however, the differences between the other combinations are not significant. The results in this paper will be used further investigation for propagation channel modeling of on-body networks.
