本文主要研究了在体通道特性与物体形态变化之间的关系。在5.8GHz下进行了分析，并采用了并行版本的时域有限差分法（FDTD）。仿真域采用了50个数字模型。有关研究的参数是路径损耗和信道容量。结果表明，对于腰围尺寸相近的模型，高度变化50 cm，可引起路径损耗指数变化20%，单位赫兹信道容量变化35%.
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.
