| Abstract(in English) | In this paper, we demonstrate the effectiveness of the measurement method in a real propagation environment by DOA measuring at 300 GHz band in multiple indoor environments using a reflector antenna with a narrow beam and mechanical horizontal directional scanning. In a conference room, differences in received power of reflected waves due to different wall materials and surface roughness were confirmed. In the LOS environment in the hallway, it was confirmed that clusters with arrival spacing of a few degrees can be observed. In the NLOS environment, we confirmed that paths reflected multiple times on walls can be observed due to the high gain characteristics of the antenna. |
