Antenna and electronic device including same

An electronic device comprising:

• a housing comprising a front plate, a rear plate facing in the opposite direction to the front plate, and a side member surrounding the space between the front plate and the rear plate;
• the side member comprising:
• a first side surface extending in a first direction and having a first length,
• a second side surface extending in a second direction perpendicular to the first direction and having a second length larger than the first length,
• a third side surface extending in parallel with the first side surface and having the first length, and
• a fourth side surface extending in parallel with the second side surface and having the second length,
• wherein the first side surface comprises 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, and
• wherein the rear plate comprises, 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 surrounded by the second conductive part and the nonconductive slit, and a second conductive area positioned outside the first conductive area across the nonconductive slit;
• a touch screen display arranged inside the housing and exposed through a part of the front plate;
• a printed circuit board comprising:
• a ground plane arranged between the front plate and the rear plate in parallel with the rear plate,
• wherein the ground plane comprises a peripheral part spaced apart from the first side surface, and
• wherein the printed circuit board comprises a conductive path extending from a first point of the peripheral part to a second point thereof toward the first side surface such that, when seen from above the rear plate, the first point overlaps with the second conductive area, and the second point overlaps with the first conductive area;
• a first flexible conductive member arranged between the first point and the second conductive area of the rear plate so as to make an electric connection therebetween;
• a second flexible conductive member arranged between the second point and the first conductive area of the rear plate so as to make an electric connection therebetween;
• a third flexible conductive member arranged between the third point and the first conductive area of the rear plate so as to make an electric connection therebetween;
• a fourth flexible conductive member arranged between the fourth point and the first conductive area of the rear plate so as to make an electric connection therebetween;
• and
• at least one wireless communication circuit arranged on the printed circuit board and electrically connected to the third point and the fourth point,
• wherein, when seen from above the rear plate, the third point and the fourth point are arranged on both sides of the conductive path, respectively.
