We have proposed an OAM-MIMO multiplexing technique as a high-capacity, point-to-point (PtP) line-of-sight wireless communication system for the rapid growth of data traffic. The propagation characteristics of the electromagnetic (EM) beams with orbital angular momentum (OAM) states are roughly divided into two distance regions, and the boundary is called the "Rayleigh length." Although EM beams with higher OAM states attenuate rapidly as they propagate in farther field regions, we show and demonstrate that we can estimate and cover them at several times the Rayleigh length. However, unideal effects (ground reflection, imperfect analog devices, antennas misalignment, etc.) can occur. To prove the feasibility of our OAM-MIMO multiplexing technique, we conducted field experiments and successfully demonstrated over 20 Gbit/s OAM-MIMO wireless transmission at the distance under 100 m-approximately six times the Rayleigh length-including OAM mode +/- 2 on a 28 GHz frequency band with the bandwidth of 750 MHz. |
