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...
The on-body radio channel performance of a small printed quasi-self-complementary ultra wideband (UWB) antenna is investigated in this paper. Measurement campaigns are performed in the chamber and in an 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. A reduction of 16.34% path loss exponent...
In this paper, the impact of different subject sleeping positions on the ultra wideband (UWB) off-body radio channel is experimentally investigated. Maximum of 15 dB path loss variation is noticed of a channel for different sleeping positions of the subject on the bed at the same location. Results and analysis show that the path loss value is dependent on the different sleeping modes and positions...
