Abstract

An electronic device is provided. The electronic device includes a housing, a touch screen display arranged inside the housing, a printed circuit board (PCB) which is arranged in parallel with a rear plate, and which includes a ground plane and a conductive path, and a wireless communication circuit arranged on the PCB. The housing includes a first side surface, a second side surface, a third side surface, and a fourth side surface. The first side surface includes a first conductive part, a first nonconductive part, a second conductive part, a second nonconductive part, and a third conductive part successively arranged between the second side surface and the fourth side surface. The rear plate includes, when seen from above the rear plate, a nonconductive slit extending from the first nonconductive part to the second nonconductive part, a first conductive area, and a second conductive area positioned outside the first conductive area across the nonconductive slit.
