Antenna structure

Abstract

An antenna structure is provided. The antenna structure includes a grounding terminal, a feeding point, and multiple antenna elements. The feeding point is arranged on a central region of the antenna structure. The multiple antenna elements are arranged on at least one surface of the antenna structure, and each of the multiple antenna elements comprises an extension portion and a radiation portion, respectively. Each extension portion extends from the central region in a generally symmetrically toward an outward direction respectively, and the extension portions form an angle with the radiation portions, causing the radiation portions to extend to a side opposite the outward direction. Less than all of the extension portion includes an inner section and an outer section, the inner section forms an angle with the outward direction, and the outer section is parallel to the outward direction, thereby the antenna structure generates an radiation pattern that is asymmetric relative to the feeding point.
