Surface and creeping waves excitation by body-worn antennas

Surface and creeping waves play an important role on-body communication channels. In this paper, we explore the characteristic of the wave on the body surface relate this to the antenna type. Simple models are used to extract the attenuation exponent and evaluate capability of the practical antennas in lunching the surface wave. Both flat and cylindrical phantoms are used in the simulations and the wave variation versus distance is investigated for each antenna.
