Daisy Chain MIMO Antenna: A Big Challenge to Full-azimuth 100 Gbps Capacity

This paper presents a new concept of large-scale MIMO systems called “Daisy Chain MIMO Antenna”. We have conducted a series of studies to confirm the validity of our proposal, which include 32 x 32 and 64 x 64 MIMO systems. Though in-depth examinations, it is clarified that the daisy chain MIMO antenna has unique features in terms of the simultaneous achievements of large gain and low correlation, which results in a MIMO antenna with Gbps-transmission rate over 360-degree communication targets in azimuth. In the current paper, we further advance the concept to accomplish a 128 x 128 daisy chain MIMO antenna system with full-azimuth 100 Gbps channel capacity.
