An analytical path-loss model for on-body radio propagation

Abstract

An analytical model for across the body surface communication systems is presented. The paper is focused on the calculation of the approximate path gain, both along and around planar and cylindrical geometries, representative of the human body for antennas polarized normal to the body surface. The model is validated at 2.45 GHz using finite-difference time-domain numerical analysis and in-situ measurements on an adult-male test subject.
