Summary:Having the unique feature of wide continuous bandwidth, millimeter-wave communication has attracted great attention from both industry and academics. However, due to the large path loss and diffraction loss, human body shadowing (HBS) has a huge impact on millimeter- wave communication and requires intensive research. In this paper, we conduct HBS measurements in three different cases at 28 GHz by using a pair of horn antennas. Based on our measurement results, we propose a simple HBS model, and then use the double-edge and the multiple-edge diffraction method to study the characteristics of HBS. The gain of HBS is generally 10 dB or greater for the 16 m LOS link. It grows with the distance between TX and RX, and a relative small gain will be obtained when people are close to the antennas and LOS path. Furthermore, human body's direction will have great impact on the effective height, which finally causes 4.63 dB loss.
