Antenna structure and electronic device including same

An electronic device comprising:

• a housing including:
• a first plate;
• a second plate facing in a direction opposite to the first plate;
• a side surface member surrounding a space between the first plate and the second plate and including a conductive portion;
• a communication module;
• an antenna structure operably connected to the communication module;
• and
• at least one processor controlling beamforming in a horizontal direction using the antenna structure or controlling beamforming in a vertical direction using the antenna structure,
• wherein the conductive portion of the side surface member includes a first area and a second area formed in a position different from the first area,
• wherein the antenna structure includes:
• first slot sets formed in the first area, a first slot set formed by combining at least two first slots extending in a first direction, a plurality of first slot sets formed with a designated gap in a second direction;
• and second slot sets formed in the second area, a second slot set formed by combining at least two second slots, a plurality of second slot sets formed with the designated gap in the second direction,
• wherein at least two first slots included in the first slot set are formed to include different lengths in the first direction each other, and at least two second slots included in the second slot set are formed to include different lengths in the second direction each other, and
• wherein the first slot set and the second slot set formed in a position corresponding to the first slot set are symmetrically formed with respect to a designated point in a virtual line passing through a center of the conductive portion.

An electronic device comprising:

• a housing including:
• a first plate,
• a second plate facing in a direction opposite to the first plate, and
• a side surface member surrounding a space between the first plate and the second plate and at least partially including a conductive portion;
• and
• at least one antenna structure disposed in at least a portion of the side surface member,
• wherein the at least one antenna structure includes:
• a conductive portion surrounding the space and including a first surface facing an outside of the electronic device,
• at least one of a first extension extending from a first end of the conductive portion and formed with a second surface at least partially facing in a direction different from a direction in which the first surface faces or a second extension extending from a second end of the conductive portion and formed with a third surface at least partially facing in a direction different from the direction in which the first surface faces, and
• the conductive portion includes a first area in which a first slot set is formed and a second area in which a second slot set is formed,
• wherein the first slot set is formed with a combination of at least two first slots formed to include different lengths in a first direction respectively,
• wherein a plurality of first slot sets is formed with a designated gap in a second direction,
• wherein the second slot set is formed with a combination of at least two second slots formed to include different lengths in the first direction respectively,
• wherein a plurality of second slot sets is formed with a designated gap in the second direction, and
• wherein the second slot set formed in a position corresponding to the first slot set includes a shape symmetrical with the first slot set with respect to a designated point in a virtual line passing through the conductive portion.
