Abstract: A multi-input multi-output antenna system capable of being disposed in an electronic device and the electronic device including the antenna system have a low-frequency antenna assembly and a high-frequency antenna assembly. The low-frequency antenna assembly includes multiple low-frequency antennas that are spaced apart from each other by a distance. The high-frequency antenna assembly includes multiple high-frequency antennas that are spaced apart from each other by a distance. One of the high-frequency antennas is structured as a low-profile dish antenna and is located between the low-frequency antennas, so that the antenna system has smaller volume and height, and better isolation and radiation patterns.

Abstract: A periodic metal array structure can be disposed between two antenna modules and include rows of metal unit assemblies that each includes metal units connected to each other in a longitudinal direction. Each metal unit has a first longitudinal strip, two first transverse strips, two second transverse strips, and two second longitudinal strips having shorter longitudinal lengths than that of the first longitudinal strip, and being respectively disposed on the left and right sides of the first longitudinal strip and respectively spaced apart therefrom by intervals at which the second transverse strips are located. The top and bottom ends of the first longitudinal strip are respectively connected with the first transverse strips. At least one first transverse strip can be connected to a first transverse strip of an adjacent metal unit. Each second transverse strip can be connected to the first longitudinal strip and a corresponding second longitudinal strip.
