Claim:
1. A dual-band antenna, comprising: a ground element; a radiation element, having a bending to form a first radiation portion and a second radiation portion, wherein the first radiation portion is symmetrical to a first reference line and has a short edge, a long edge electrically connected to the second radiation portion, a first side edge and a second side edge, a feeding point is adjacent to the ground element and disposed on the short edge of the first radiation portion, a width of the first radiation portion is increased along a direction far away from the ground element and defined by the first side edge and the second side edge of the first radiation portion, the second radiation portion forms an orthogonal projection on the ground element and has a first edge electrically connected to the first radiation portion, a second edge and a third edge, and the second edge and the third edge of the second radiation portion are adjacent to the first edge of the second radiation portion; at least one open slot, passing through the second radiation portion to form a meandering structure of the second radiation portion; and a first extension element, electrically connected to the first radiation portion and intersecting with the first radiation portion at the first reference line, wherein a width of the first extension element is gradually increased along the direction far away from the ground element.
