Claim:
1. A wearable electronic device, comprising: a body including a conductive frame and a conductive back cover, the conductive frame includes a feeding point and at least a grounding point to form a first current path and a second current path thereon, the conductive frame forms a loop antenna which generates two resonant modes via the first current path and the second current path to operate in a first band and a second band; a wearing element connected to the body; a physiological sensor electrically connected to the conductive frame and the conductive back cover; and a system ground plane, wherein when the physiological sensor senses the physiological signal via the conductive frame and the conductive back cover, the system ground plane is DC blocked against the conductive frame and the conductive back cover, wherein when the conductive frame is operated in the first band and the second band, the system ground plane is AC conducted with the conductive frame and the conductive back cover.
