Abstract
Embodiments of this application provide an electronic device. The electronic device includes a first antenna and a second antenna. The first antenna uses conductive parts of a side frame of a first housing as a first radiator and a parasitic stub. The second antenna uses a conductive part of a side frame of a second housing as a second radiator, and the second radiator and the parasitic stub are adjacently disposed. The electronic device may be a foldable electronic device.
