Electronic device comprising radiating element

An electronic device comprising:

• a housing including a first plate facing a first direction, a second plate facing a second direction opposite to the first direction, and a side member formed facing a third direction to surround a space between the first plate and the second plate;
• a gap region formed by spacing apart or segmenting at least a portion of the housing;
• a printed circuit board (PCB) disposed inside the housing;
• an antenna structure including a power feeding portion and a grounding portion, at least a portion of the antenna structure being electrically connected to the PCB;
• and
• a radiating element electrically connected to the power feeding portion or the grounding portion, the radiating element being positioned such that at least a portion of the radiating element overlaps the gap region when the electronic device is viewed in the first direction, the second direction, or the third direction,
• wherein the gap region comprises a second gap region formed as the second plate and the side member are spaced apart from each other, and
• wherein the radiating element comprises a second radiating element positioned on a side toward the second direction with respect to the PCB.
