A multi-band antenna has a radiating conductor, a feeding conductor and a short conductor. The feeding conductor and the short conductor connect to one side of the radiating conductor, which are arranged close to each other. The radiating conductor has a slot containing an opening portion, a first extension portion and a second extension portion communicating with each other. The opening portion opening at the other side of the radiating conductor and the first and second extension portions extend to different directions. The second extension portion defines a short portion on the radiating conductor. The multi-band antenna is divided by the slot to form an inverted-F portion being similar to an inverted-F antenna to resonate at a first frequency band, and a loop portion being similar to a loop antenna to resonate at a second frequency band.
