On-body radio channel measurements for three different human body sizes

In this paper, the effects of different body sizes and shapes on the narrowband (2.45 GHz) on-body radio propagation channels are investigated. Three different human body sizes (thin, medium build and fatty/larger size) are investigated. Experimental investigation is performed using Printed Monopole antennas in the indoor environments. Thirty four different receiver locations on the front part of the body are considered for calculating the path loss. Results show that due to three different human body shapes maximum of 20.3% variation in path loss exponent is observed.
