Claim:
1. An antenna structure comprising: a main portion comprising a flat section, the flat section being substantially a right-angled polygons sheet; a first radiating portion connected to the main portion; a second radiating portion connected to the main portion and opposite to the first radiating portion; and a coupling portion spaced from and coplanar with the main portion and opposite to the second radiating portion, the coupling portion comprising a first coupling section being substantially an inverted right-angled polygons sheet and spaced from and coplanar with the flat section, a low edge and an up edge of the first coupling section collinear with an up edge and a low edge of the flat section, respectively, a bevel edge of the first coupling section adjacent to a bevel edge of the flat section; wherein the main portion and the first radiating portion excite a low frequency mode, the main portion, the first radiating portion, the second radiating portion, and the coupling portion excite a high frequency mode, and when the antenna structure is interfered by an interference generated by a user's human body when close to the user's human body, the coupling portion transmits the interference to ground.
