Abstract

Ultra wideband (UWB) is a promising technology for wireless body area networks (WBANs). This paper investigates the wave propagation in the frequency range of 1-6 GHz for non-line-of-sight (NLOS) channels from front to back of a human body by considering different wave polarizations: perpendicular and tangential with respect to the body. Time domain electromagnetic (EM) simulation using the anatomical model of a human body assuming frequency dependent tissue properties is conducted. A significant enhancement of the on-body communication link is identified by exploiting the transceiver antennas at the perpendicular to body polarizations. As the results, the radiograph of the energy density and delay spread of the NLOS channels with different antenna polarizations are presented.
