ABSTRACT:
A multiband antenna includes a conductive sheet, a feeding point, and a grounding point. The conductive sheet defines a first slot, a second slot, a third slot, a fourth slot, a fifth slot, a sixth slot, and a seventh slot thereon. The second slot and the third slot extend from a same short side of the first slot and are parallel to each other. The fourth slot, the fifth slot, the sixth slot, and the seventh slot extend perpendicularly from a short side of the third slot away from the first slot in sequence. The feeding point is formed on the conductive sheet at a long side of the first slot away from the third slot. The grounding point is formed on the conductive sheet at a margin of the slots different from the location of the feeding point.
