    [Abstract]
     
    This paper presents an evaluation on how Norton surface waves can be used to analytically model the on-body propagation in wireless body area networks. Based on a brief review of the Norton surface wave theory the general problem as defined for terrestrial propagation by Sommerfeld is unified taking into account the further extensions by Norton and Bannister which motivates its evaluation for on-body propagations. A discussion of Sommerfeld's numerical distance reveals useful properties to evaluate the capability of a certain configuration to excite Norton surface waves in specific on-body scenarios. Based thereon antenna design guidelines for on-body propagation links can be derived. All investigations are carried out for human muscle, skin and fat tissues in the frequency range from 0.4 GHz to 60 GHz. A comparison of the simplified model consisting of a planar homogeneous ground to a realistic inhomogeneous human body model shows good results for the attenuation of the electric field strength along the on-body path.

    [Abstract]
     

    Within the scope of on-body communications an approach is presented which is capable to describe the radiated on-body field of arbitrarily shaped antenna structures. The method is based on a segmentation of the excited current distribution on the antenna body by a finite number of small electric dipoles. To consider the presence of the human body, which affects the underlying radiation mechanism significantly, the model is implemented by the use of the Norton surface wave theory. Based thereon, a method is presented to model the onbody far field of an antenna by two equivalent electric dipoles, a TM and a TE source. Based on this assumption the directivity and the effective antenna area are defined for on-body propagation scenarios. The radiation characteristic of body worn antennas is discussed in terms of their radiation characteristic using the example of tilted half-wave dipoles and a planar inverted-F antenna. The last part of the study discusses a pathloss model which is calculated from the underlying antenna parameters. Numerical full-wave simulations, based on the FDTD method, and measurements in an anechoic chamber, verify the results.
