Embodiments of the present invention provide a millimeter wave MIMO antenna and a millimeter wave MIMO communication device. The antenna consists of four branch areas assembled in a cross shape, each branch area includes a trapezoidal area close to the center of the cross, a rectangular area away from the center of the cross, and a strip area connecting the trapezoidal area and the rectangular area. The long sides of the corresponding rectangular areas are opposite to each other. The antenna includes: a top metal plate, a grounded bottom metal plate, and a dielectric substrate between the bottom metal plate and the top metal plate; wherein, the top metal plate is partially hollowed out corresponding to four trapezoidal regions, forming four trapezoidal gaps; the bottom metal The part of the plate corresponding to the four rectangular areas is hollowed out to form four rectangular gaps; the surface of the dielectric substrate facing the bottom metal plate is pasted with four metal patches, and the metal patches are set in the rectangular area; the bottom metal plate, the dielectric substrate and the top metal plate The overall structure has metal vias 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.
