A printed antenna includes a feed portion and a radiating portion. The feed portion feeds electromagnetic signals, and includes a feed end and a connection end. A width of the feed portion is gradually increased from the feed end to the connection end. The radiating portion includes a first radiator and a second radiator. The first radiator is elongated, and connects to the connection end of the feed portion. One end of the second radiator is connected to the first radiator, and the other end is free. The free end is bend and bent along the feeding portion, and defines a slot between the second radiator and the first radiator and the feeding portion.
