Abstract
Ultra-wideband (UWB) has potential applications in variety of medical areas such as implant wireless sensors, microwave hyperthermia, imaging and radar. The wave propagation inside human body must be known for an efficient system design for the different applications. In this paper, UWB signal propagation inside human body is characterized for line-of-sight (LOS) scenario inside chest of a human model for the frequency range of 100– 1000 MHz. The radiograph of UWB power and the spectrum of the penetrated wave into body are analyzed. The power delay profile (PDP) and the root-mean-square (RMS) delay spread of the in-body channels are obtained for the potential applications on wireless medical implant communications.
