ABSTRACT: In this paper, on-body radio channel performance of a compact ultra
wideband (UWB) antenna is investigated for body-centric wireless
communications. Measurement campaigns were first done in the chamber and then
repeated in an indoor environment for comparison. The path loss parameter for
eight different on-body radio channels has been characterized and analyzed. In
addition, the path loss was modeled as a function of distance for 34 different
receiver locations for propagation along the front part of the body. Results
and analysis show that, compared with anechoic chamber, a reduction of 16.34%
path loss exponent is noticed in indoor environment. The antenna shows very
good on-body radio channel performance and will be a suitable candidate for
future efficient and reliable body-centric wireless communications.
