Abstract
An electronic device including a ground plane, a metal frame, a plurality of radiation elements and a switching circuit is provided. A first end of a frame element in the metal frame is connected to the ground plane, and a second end of the frame element is an open end. Each of the radiation elements is spaced by a coupling distance from the frame element. The switching circuit transmits a feeding signal to one of the radiation elements. When the feeding signal is transmitted to a first radiation element among the radiation elements, the electronic device operates in a first band and a second band through the first radiation element and the frame element. When the feeding signal is transmitted to a second radiation element among the radiation elements, the electronic device operates in a third band and a fourth band through the second radiation element and the frame element.
