Abstract

Ultra wideband (UWB) is an emerging technology with promising applications in wireless body area networks (WBANs). Detailed understanding of the propagation mechanism of UWB signal around human body is essential for the development of wearable sensors. However there are currently limited studies describing UWB signal propagation around human body. In this paper, the favorable antennae polarization for effective transmission of signal to receiver is investigated through numerical simulations. The results showed that antennae oriented in perpendicular polarization with respect to body surface provide a lower path loss as compared to horizontal polarization.
