本文提出了一种在5 GHz频段的无线电波传播特性的调查，在一个住宅两层楼的房子。我们研究了当发射器和接收器分别位于第一层和第二层时入射波的三维角谱。首先，确定包含诸如床、沙发和桌子的家具的测量的“家庭环境”中的相关性以确认准静态环境。然后，通过使用八元件八木宇田天线作为接收天线进行3-D角谱测量。此外，4 × 4 MIMO信道容量估计在每个仰角通过使用仰角谱和传播特性之间的第一和第二层进行了评估。结果表明，仰角方向的信道容量受发射天线方向的影响很大。
This paper presents an investigation of radio-wave propagation characteristics in the 5 GHz band in a residential two-story house. We investigated the 3-D angular spectra of incident waves when a transmitter and a receiver were situated on the first and second floors, respectively. First of all, correlation in the measured "home environment" containing furniture such as beds, a sofa and tables was determined to confirm a quasi-static environment. Then, 3-D angular spectra measurements were performed by using an eight-element Yagi-Uda antenna as a receiving antenna. Furthermore, the 4-by-4 MIMO channel capacity at each elevation angle was estimated by using elevation angular spectra and the propagation characteristics between the first and second floors were evaluated. The results indicated that the channel capacity in the elevation direction was strongly influenced by the direction of the transmitting antenna.
