A dual-band antenna includes a first radiating portion, a second radiating portion and a third radiating portion. The second radiating portion includes a first section extending perpendicularly from a free end of the first radiating portion, and a second section extending substantially perpendicular to the first section and opposite to the first radiating portion from the first section. The third radiating portion includes a first segment extending in alignment with the first radiating portion from the free end of the first radiating portion, a second segment extending perpendicularly towards the second section from the first segment and spaced away from the first section and a third segment extending perpendicularly back to the first section from the second segment and spaced away from the second section. A feeding point is disposed at a junction of the first, second and third radiating portion.
