A dual-band antenna (10) is disposed on a substrate (20), for transceiving electromagnetic signals of different frequencies. The dual-band antenna includes a grounded portion (12), a feeding portion (14), and a radiation body (16). The feeding portion is adjacent to the grounded portion. The radiation body electronically connected to the feeding portion, includes a first radiation portion (160) and a second radiation portion (162). The first radiation portion includes a first free end (160c), a first connecting end (160a) electronically connected to the feeding portion, and a serpentine portion (160b) between the first free end and the first connecting end. The second radiation portion, includes a second connecting end (162a) electronically connected to the first connecting end, and a second free end (162b), wherein the first free end and the second free end face each other and a gap (18) is formed therebetween.
