Spherical Cap Structure MIMO-OTA Apparatus for Generating the Cluster Propagation Environments
Kazuhiro Honda (Univ. of Toyama) AP2023-8
Abstract (in Japanese) (See Japanese page) 
(in English) In order to realize the cluster propagation environments that forms a Gaussian distribution in the vertical and horizontal directions, this paper presents a three-dimensional MIMO-OTA apparatus with the scatterer antennas on a spherical cap. OTA testing of MIMO channel capacity for DUT antenna according to the incoming wave from high elevation angles is performed by rotating the DUT antenna placed in the center of the fading emulator under evaluation in relation to the direction of the incoming wave while the scatterer antennas on a spherical cap are fixed. To investigate the appropriate scatterer arrangement, the channel capacity of a 4-element MIMO array antenna was performed through the Monte Carlo simulation considering a spherical cap structure. Analytical results reveal that the MIMO channel capacity can be evaluated with high accuracy by setting the angle of the spherical cap to 70 degrees, regardless of the density of the scatterer arrangement.
