The invention provides a dual-band antenna. The dual-band antenna comprises a first antenna part, a second antenna part and a grounding part. The first antenna part comprises a signal feed-in part, afirst radiator and a second radiator, wherein the signal feed-in part is electrically connected to the signal feed-in point so as to receive an antenna signal. The first radiator constitutes an antenna device, such as a planar inverted F-shaped antenna. One end of the antenna device is electrically connected to the signal feed-in part, and the other end of the antenna device is electrically connected to the grounding part. The second radiator and the antenna device are respectively arranged on two opposite sides of the signal feed-in part. The second antenna part comprises a third radiator anda fourth radiator. The second radiator and the third radiator form a capacitive feed-in structure. One end of the fourth radiator is electrically connected to the capacitive feed-in structure, and the other end of the fourth
