This paper presents results of a systematic 2×2 MIMO channel measurement campaign, which has been carried out in order to analyze the impact of human body shadowing (HBS) on the 60 GHz wideband channel. A piecewise linear and two analytical models, namely the double knife-edge (DKE) model and a cylinder approach incorporating the uniform theory of diffraction (UTD), are used to approximate and to predict the measurement curves. We propose measures to quantify the degree of match between attenuation curves in the millimeter wave frequency band and use them to evaluate the model results with respect to different scenario groups. The presented results are beneficial to refine existing diffraction models regarding the prediction of HBS effects.
