Abstract
A study of human body influence on off-body ranging
performance of a low profile UWB antenna is presented. Antenna
ranging performance is reported for 10 volunteer wearers and
for two different placements. Antenna was especially designed for
WBAN applications and is immune to body influence even when
in direct skin contact. Average ranging error value below 5 cm is
observed for the majority of angles in the front antenna plane
with standard deviation of the same order. The study shows that
the antenna ranging precision depends more on the body
placement than on the distance from the body.
