ANTENNA STRUCTURE

摘要

An antenna structure (S) includes a board unit (1) and a coil unit (2). The board unit (1) includes a metal board (10) and an insulating board (11) connected with or adjacent to the metal board (10), and the coil unit (2) is disposed beside the same side of the metal board (10) and the insulating board (11). In one embodiment, when one narrow side (100) of the metal board (10) and one narrow side (100) of the insulating board (11) connects with each other, the coil unit (2) is disposed right under the commissure of the metal board (10) and the insulating board (11). In addition, more than half or half of the area of the coil unit (2) is covered by the insulating board (11), and less than half or half of the area of the coil unit (2) is covered by the metal board (10). The current direction (L1) on the metal board (10) and the current direction (L2) on the coil unit (2) are the same as clockwise or counterclockwise.
