Abstract

Abstract: The block diffraction attenuation characteristics of wood board, mirror and white iron board were studied based on 45 GHz millimeter wave indoor communication measurements. According to different block material, the 3-ray and 4-ray block diffraction models were proposed, respectively. The rectangular block diffraction measurement experiments were carried out on 12 mm thick wood board, 6mm thick mirror, and 0.35 mm thick white iron board. Experiment shows that the average transmission attenuation coefficient of 45 GHz millimeter wave blocked by 12 mm thick rectangular wood board is about -4.28 dB, and the average error between the attenuation measurement results and the 4-ray model simulation results is about -0.02 dB. The average transmission attenuation coefficient of 45 GHz millimeter wave blocked by 0.35 mm thick rectangular white iron board is about -18.2 dB. In the case of the mirror far away from the antennas, the measured average transmission attenuation by the mirror surface is 1-2 dB larger than that of the negative one. When the mirror is near any set of antennas,the measured value by the mirror surface is similar to that of the white iron board.
