Abstract (in Japanese) (See Japanese page) 
(in English) In UCA-based OAM, the misalignment of the beam axis due to wind causes inter-mode interference. So far, we have clarified that the adoption of multiple UCAs is effective to alleviate such interference thanks to an enhanced degree of freedom in the antenna radius. In this report, we investigate the impact of the misalignment of the beam axis on the system capacity of OAM-MIMO which can further enhance the system capacity of UCA-based OAM with multiple UCAs.
