Abstract: An antenna includes a first antenna element, a second antenna element, and a first coupler. The first antenna element includes a first radiation conductor and a first feeder line and resonates in a first frequency band. The second antenna element includes a second radiation conductor and a second feeder line and resonates in a second frequency band. The second feeder line is coupled to the first feeder line such that a first component, which is one of a capacitance component and an inductance component, is dominant. The first coupler couples the first and second feeder lines such that a second component different from the first component is dominant. The first and second radiation conductors are arranged at an interval of ½ or less of a resonance wavelength in a first direction. The first and second radiation conductors are arranged to be shifted in a second direction intersecting the first direction.

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.
