Abstract
A wearable electronic device includes a middle frame, a metallic side wall, a dielectric element, and a antenna wiring circuit. The metallic side wall is disposed at one side of the middle frame and has a slot. The dielectric element is disposed at the slot and electrically isolates the metallic side wall and the middle frame. The antenna wiring circuit is disposed at the dielectric element and comprises a antenna pattern. The antenna pattern comprises first and second metal portions. The first metal portion comprises a slit surrounded by first to third segments. The first segment has a signal feeding terminal. The second metal portion is connected to the third segment and is located in the slit. The metallic side wall performs coupled resonant with the first metal portion and the second metal portion to generate a resonant frequency band.
