UWB propagation channel measurements for WPAN scenarios

Abstract

In this paper, we perform UWB propagation channel measurements for scenarios when transmit antenna is located on a human body. Measurements were done for different antenna locations: on a head, on a torso, on a belt. For reference purposes we measured signal propagation when the transmit antenna was in free space. We investigated influence of a human body at the link budget for a different frequencies and antenna polarizations. The minimal blockage was found for the antenna located on a head. For a vertically polarized antenna located on a torso or on a belt the signal blockage in backwards and sideward directions is smaller then for horizontally polarized antenna.
