Effect of the antenna-body distance on the on-ext and on-on channel link path gain in UWB WBAN applications

This paper investigates the effect of the operation distance (i.e., practical use) between an antenna and a human body on wireless body area network (WBAN) channel path gain. Different use cases in WBAN on-external (ext) and on-on links with different antenna-body distances for ultra wideband (UWB) technology are considered. These studies are carried out with two types of planar UWB antennas in the vicinity of a real human body. Corresponding scenarios are repeated by computer simulations, and differences between these environs (i.e., challenges in the modelling of the measurement situation) are analysed and discussed.
