A dual-band antenna is provided and has a feed base portion, a low-frequency radiation portion and a high-frequency radiation portion. A first end of the feed base portion is bent and extended to form the low-frequency radiation portion which has a first transverse portion, a first longitudinal portion, a second transverse portion, a second longitudinal portion and a third transverse portion. A second end of the feed base portion is bent and extended to form the high-frequency radiation portion which has a third longitudinal portion, a fourth transverse portion and a fourth longitudinal portion. The feed base portion is further bent and extended to form a feed end. The dual-band antenna of the present invention has a roundabout bent structure, so that the dual-band antenna has a better effect for transmitting and receiving electro-magnetic signals of two frequency bands of 900 MHz and 1800 MHz. |
