Abstract :
In this paper, the propagation channel between two half-wavelength dipoles at 2.45 GHz, placed near a human body is studied. Measurements are performed on a real human, considering different parts of the body separately. The measurement results are compared with FDTD simulations, using an anatomically correct model of the human body. Channel characteristics are extracted from the measurement and simulation data. A semi-empirical path loss model is proposed and lognormal behaviour is validated.
