Simulation of path loss between biocompatible antennas embedded in homogeneous human tissues and comparison of their specific absorption rate

A wireless body area network (WBAN) is a network, consisting of nodes that communicate wirelessly and are located on or in the body of a person. In this paper, the authors study the wave propagation using biocompatible folded slot dipole antennas within various lossy human tissues such as the muscle tissue, skin and the fat layer and obtain their path loss (PL) and specific absorption rate (SAR) by means of simulations, and fit a suitable path loss model to the propagation scenario at hand.
