Wearable electronic device comprising an antenna

A wearable electronic device comprising:

• a metal frame forming at least a portion of a side surface of the wearable electronic device, wherein at least a portion of the metal frame is used as an antenna radiator;
• a rear cover forming a rear surface of the wearable electronic device;
• a display mounted on the metal frame;
• a first printed circuit board (PCB) disposed between the display and the rear cover;
• a second PCB disposed between the display and the first PCB, wherein the second PCB is electrically connected with the first PCB and includes a ground;
• a first connection member at least partially disposed on a surface of the second PCB, and electrically connected with the ground;
• a second connection member disposed to be in contact with the first connection member;
• and
• a wireless communication circuit configured to feed power to a first point of the antenna radiator for transmitting and/or receiving the signals of a first frequency band,
• wherein the second connection member is electrically connected with the metal frame, such that the ground of the second PCB is electrically connected with the metal frame via the first connection member and the second connection member and the antenna radiator is configured to transmit and/or receive signals of the first frequency band.
