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.

Abstract: A multiband antenna includes a first radiator, a feed element, a first ground element, a second radiator, a connecting element, and a second ground element, wherein the first radiator is made of a metal plate. The feed element is electrically connected to the first radiator and is adapted to feed a signal. The first ground element is electrically connected to the first radiator. The second radiator is made of a metal plate and surrounds an outer side of the first radiator, wherein the first radiator and the second radiator are spaced by an interval. The connecting element is electrically connected to the first radiator and the second radiator. The second ground element is electrically connected to the second radiator. In this way, the multiband antenna is suitable for transmitting signals in multiple frequency bands.
