Antenna structure

Abstract

An antenna structure includes a ground terminal, a feed point, and multiple antenna units. The feed point is arranged on a central region of the antenna structure. The multiple antenna units are arranged on at least one surface of the antenna structure. Each of the multiple antenna units includes an extension portion and a radiation portion, respectively. Each extension portion symmetrically extends from the central region toward an external direction respectively. The extension portion form a corner with the radiation portion, and the radiation portion to extend to a side relative to the external direction. A few of the extension portions include an inner section and an outer section, the inner section forms an included angle with the external direction, the outer section is parallel to the external direction, and the antenna structure generates a radiation pattern that is asymmetrical relative to the feed point.
