Abstract

In this paper a hybrid method for modelling on-body propagation channel has been presented. The original problem is split into two sub-domains: the antenna is analyzed with the commercial software CST, while the human body is handled with the FDTD; the equivalence principle is used as interface between the two sub-domains. The method has been applied to analyze a typical on-body scenario at the unlicensed frequency of 2.4 GHz. The variation of the path loss with the distance transmitter-receiver has been evaluated, placing the transmitter antenna on the belt, and moving the receiver probe on the trunk.
