Abstract (in Japanese) (See Japanese page) 
(in English) Recently, wireless communication using Orbital Angular Momentum (OAM) has drawn much attention as an
emerging candidate of 5G/B5G technology. OAM is a physical property of electro-magnetic waves that are characterized by a
helical phase front in the propagation direction. Since the characteristic can be used to create multiple orthogonal channels,
wireless communication using OAM can increase radio spectrum efficiency and expand the capacity of the scarce radio
spectrum. To explore these possibilities, in the work reported in this paper we investigated the performance of the OAM
multiplexing with an experimental study. In particular, we present a simple but practical Rx antenna design method. Exploiting
the fact that there are specific location sets with phase differences of 90 or 180 degrees, the method allows each OAM mode to
be received at its high SNR region. We confirm the feasibility of OAM multiplexing in a proof of concept experiment at 5.2
GHz. The effectiveness of the proposed Rx antenna design method is validated by computer simulations using experimental
results.
