Electronic device

An electronic device includes a metal back cover and an antenna module. The metal back cover includes a slit. The antenna module is located in and 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 bending shapes, and the first section has a feeding end. The first ground radiator is disposed beside the antenna radiator, and the first section is located between the third section and the first ground radiator. The connecting radiator connects the third section and the first grounded radiator, so that a first slot is formed between the first grounded radiator, the first section, the second section, and a part of the third section. The width and length of the first slot is associated with a center frequency and impedance matching of a second high frequency band.
