Abstract: An antenna array device provided, which includes a substrate, multiple antenna elements, a metal ground plate and a first isolation unit group. The multiple antenna elements are disposed on a first surface of the substrate. The multiple antenna elements have a first polarization direction and a second polarization direction opposite to the first polarization direction. The first isolation unit group is disposed between adjacent two of the multiple antenna elements. An arrangement direction of the first isolation unit group is perpendicular to the first polarization direction and the second polarization direction. The first isolation unit group is two isolation units which are adjacent, each of which comprises an outer end and an inner end opposite to the outer end. The inner end is connected to the metal ground plate disposed on a second surface of the substrate via a second via.

Abstract: An antenna structure is provided, which includes a substrate, an antenna unit and a metal ground. The substrate includes a first surface and a second surface; the antenna unit disposed on the first surface includes a radiation part, a feeding part and a feeding line, where the feeding line includes a first transmission line and a second transmission line that are perpendicular to each other and connected to each other, and the first transmission line is connected to the radiation part via the feeding part; and the metal ground disposed on the second surface has an edge which is perpendicular to projection of the radiation part to the metal ground; and a resonance slot is disposed on the metal ground, and its position corresponds between projection of the second transmission line to the metal ground and the edge.
