Evaluation of human body shadowimg loss in an indoor environment

In this paper, we discuss the human body shadowing loss characteristics by finding the received signal using the Finite Difference Time Domain (FDTD) method and the actual measurement in three-dimensional indoor environments. We show the human body shadowing loss when a single human body moves between transmitting and receiving antennas. Furthermore, we show the human body shadowing loss characteristics when multiple human walk and consider the relationship between the first Fresnel zone and the human body shadowing loss.
