Abstract :
This paper presents a structured evaluation of the Norton equations to describe the propagation of electromagnetic waves along the human body surface. In conjunction with this theory an antenna de-embedding of dipole antennas is proposed and a simple pathloss channel model for a vertical and horizontal orientated half-wave dipole in close proximity to a homogeneous phantom is developed. Furthermore the influence of the air-phantom boundary is verified to show different physical propagation conditions which should be considered for future antenna design approaches.
