A 60GHz line-of-sight 2x2 MIMO link operating at 1.2Gbps

We report first experimental results from a hardware prototype of a millimeter wave line-of-sight (LOS) 2x2 MIMO link. The proposed architecture uses antenna element spacing derived from the principles of diffraction limited optics to establish multiple parallel data channels. Operation at millimeter wave carrier frequencies reduces the antenna array size to reasonable dimensions. The proposed system architecture is scalable to larger one dimensional and two dimensional arrays supporting data rates ≫160Gbps. This paper presents the design and characterization of a hardware prototype 2x2 LOS MIMO link operating at 1.2Gbps.
