Abstract (in Japanese) (See Japanese page) 
(in English) In uniform circular array-based orbital angular momentum (UCA-based OAM), the adoption of multiple UCAs is effective because an enhanced degree of freedom in the antenna radius alleviates the fluctuation of the transmission performance according to the OAM mode number or the number of antenna elements. In this report, we investigate the impact of the misalignment of the beam axis on the system capacity in OAM multiplexing with multiple UCAs, and clarifies the effectiveness of multiple UCAs in the presence of its misalignment.
