60GHz has been attracting significant attentions for ultra-broadband WLAN applications because 60GHz band is available for unlicensed use on a world-wide basis.However,60GHz WLAN has some disadvantages, such as significant shadowing loss caused by a moving human body and large free space loss.To develop anti-shadowing techniques near the 60GHz band,it is required to characterize features of shadowing loss caused by a moving human body and develop a calculation model for performance evaluation of countermeasures against the shadowing loss.This paper proposes a knife cutting model based on ray tracing method.which is suitable for solving the problem of shadow loss caused by a moving human body to 60GHz WLAN.calculation model for shadowing loss caused by a moving human body in 60GHz WLAN.Through the comparison between the calculated results and measured results,the proposed calculation model can be used for ray-tracing simulations when the angle between a LOS path and a direction of a moving human body is 30 deg and 60 deg.
