Abstract :
A numerical investigation focusing on the correlation between on-body channel characteristics and the morphological variation of body is presented in the paper. The analysis has been carried out at 5.8GHz and a parallel version of Finite Difference Time Domain (FDTD) has been employed. Fifty digital phantoms are adopted in the simulation domain. Parameters explored for the concerned study are path loss and channel capacity. Results demonstrate that for models with similar dimensions around waist, a change of 50cms in height can cause a variation of 20% in path loss exponent and 35% in channel capacity per unit hertz.
