Ultra wideband on-body radio radio propagation channels study for different real human test subjects with various sizes and shapes

In this paper, the effects of eight different human body sizes and shapes on the ultra wideband (3-10 GHz) on-body radio propagation channels are investigated. Eight different real human body shapes and sizes are investigated. Experimental investigation is performed using a pair of Tapered Slot Antennas (TSA) in the indoor environment. 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 due to eight different types of human body shapes and sizes maximum of 37.6% variation in path loss exponent is observed. Variation of path loss for eight different ultra wideband on-body radio propagation channels of eight different human test subjects is also investigated.
