Wearable electronic device

Abstract

A wearable electronic device including a metal ring-shaped frame, a conductive film, a grounding element and a signal element is provided. The conductive film is arranged in the metal ring-shaped frame, and the conductive film and the metal ring-shaped frame are spaced apart by a predetermined gap to constitute a resonant cavity. The grounding element is arranged in the metal ring-shaped frame and coupled with the metal ring-shaped frame and the conductive film. The signal element is arranged in the metal ring-shaped frame and coupled between the metal ring-shaped frame and a circuit board. The signal element and grounding element constitute a closed resonant cavity with a specific length therebetween for serving as an antenna of the wearable electronic device.
