A dual-band antenna can be used in wireless communications under Bluetooth and IEEE 802.11a/b/g standards includes a rectangular base ( 1 ) forming a transverse bar ( 5 ) and a grounding bar ( 41 ) extending therefrom in a same direction, a radiating portion ( 2 ) arranged distantly above the base, an interconnection bar ( 3 ) connecting the base and the radiating portion and a feeder cable ( 6 ). The radiating portion includes a first and a second radiating arms extending from the interconnection bar in opposite directions. The first and the second radiating arms, the interconnection bar, the transverse bar, the grounding portion and the feeder cable corporately form a first and a second inverted-F antennas respectively operating at a lower frequency band and a higher frequency band.
