Abstract
An antenna structure includes a board unit and a coil unit. The board unit includes a metal board and an insulating board connected with or adjacent to the metal board, and the coil unit is disposed beside the same side of the metal board and the insulating board. In one embodiment, when one narrow side of the metal board and one narrow side of the insulating board connects with each other, the coil unit is disposed right under the commissure of the metal board and the insulating board. In addition, more than half or half of the area of the coil unit is covered by the insulating board, and less than half or half of the area of the coil unit is covered by the metal board. The current direction on the metal board and the current direction on the coil unit are the same as clockwise or counterclockwise.
