Electronic device
An electronic device is provided. The electronic device includes a metal housing, an insulation element, and an antenna unit. The insulation element is disposed on the metal housing and includes a first heat dissipation hole. The antenna unit is disposed on the insulation element and includes a radiation portion and a feeding portion. The radiation portion is composed of a conductor. The feeding portion is electrically connected to the radiation portion and a grounding plane. In this way, according to the electronic device, space configuration inside the electronic device is saved and a shielding effect of the metal housing is prevented from affecting stability of sending and receiving a signal.
