The front cover covers the metal back cover and includes a frame area. The metal wall is disposed between the metal back cover and the front cover, and forms a metal cavity corresponding to the frame area together with the metal back cover. Each of the at least one antenna radiator is disposed in the metal cavity, is connected to a first side wall of the metal back cover, and is spaced apart from the metal wall by a distance.

Abstract: An electronic device includes a metal back cover and an antenna module. The metal back cover includes a slit. The antenna module is separated from the metal back cover and disposed far away from the slit. The antenna module includes an antenna radiator, a first ground radiator, and a connection radiator. The antenna radiator includes a first section, a second section, and a third section that are sequentially connected and form bends, and the first section has a feeding end. A first slot is formed between the first ground radiator, the first section, the second section, and a part of the third section.
