  An analytical model for estimating the link loss for the on-body wave
propagation around the torso is presented. The model is based on the
attenuation of the creeping waves over an elliptical approximation of the human
torso and includes the influence of the arms. The importance of including the
arms' effect for a proper estimation of the link loss is discussed. The model
is validated by the full-wave electromagnetic simulations on a numerical
phantom.
