Abstract

A wearable electronic device is disclosed. Wearable electronic device includes a metal casing, a dielectric support part, a frame-shaped metal part, a dielectric sidewall and a first antenna wired circuit. The metal casing is electrically connected to the system ground. The dielectric support part is disposed on the metal casing. The frame-shaped metal part is disposed on the dielectric support part. One side of the frame-shaped metal part is electrically connected to the metal casing and another side of the frame-shaped metal part has a slot. The dielectric sidewall is surrounding within the metal casing. The first antenna wired circuit is disposed on the inner surface of the dielectric sidewall and insulated from the metal casing. The first antenna wired circuit is near the slot. The first antenna wired circuit and the frame-shaped metal part resonate a first resonant frequency band.
