Abstract

The embodiment of the invention provides a millimeter wave multiple-input-multiple-output antenna and millimeter wave multiple-input-multiple-output communication equipment. The antenna comprises fourbranch areas spliced in a cross shape, each branch area comprises a trapezoidal area close to the center of the cross shape, a rectangular area far away from the center of the cross shape and a strip-shaped area connecting the trapezoidal area and the rectangular area, and the upper bottom of the trapezoidal area is opposite to the long side of the corresponding rectangular area. The antenna comprises a top-layer metal plate, a grounded bottom-layer metal plate and a dielectric substrate located between the bottom-layer metal plate and the top-layer metal plate, wherein the parts, corresponding to the four trapezoidal areas, of the top metal plate are hollowed out to form four trapezoidal gaps; the parts, corresponding to the four rectangular areas, of the bottom layer metal plate are hollowed out to form four rectangular gaps; four metal patches are attached to the surface, facing the bottom-layer metal plate, of the dielectric substrate, and the metal patches are arranged in the rectangular area; and the overall structure of the bottom metal plate, the dielectric substrate and the top metal plate is provided with metal through holes arranged around the edge of the branch area.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, relate to a millimeter wave MIMO antenna and a millimeter wave MIMO communication device.
