Arrangement structure for communication device and electronic device including the same

An electronic device comprising:

• a housing comprising:
• a front surface plate;
• a rear surface plate facing toward the opposite direction of the front surface plate;
• and
• a side surface member surrounding a space between the front surface plate and the rear surface plate, the side surface member comprising a substantially rectangular shape when viewed above the front surface plate, the side surface member comprising:
• a first portion comprising a first length and extending in a first direction;
• a second portion comprising a second length longer than the first length and extending in a second direction perpendicular to the first direction;
• a third portion comprising the first length and extending in the first direction in parallel with the first portion;
• and
• a fourth portion comprising the second length and extending in the second direction in parallel with the second portion;
• a first substrate arranged in the space;
• a first wireless communication circuit mounted on the first substrate, electrically connected with a first point of the first portion of the side surface member, and configured to provide wireless communication of a first frequency band;
• a second substrate arranged between the first portion and the second portion in the space in parallel with the rear surface plate, the second substrate comprising:
• a first side extending along a part of the first portion, a second side extending along the second portion;
• a third side extending in parallel with the first side;
• and a fourth side extending in parallel with the second side;
• a first antenna array arranged to form a beam pattern in a direction from the first side of the second substrate toward the first portion;
• a second antenna array arranged to form a beam pattern in a direction from the second side of the second substrate toward the second portion;
• a third substrate arranged between the second portion and the third portion in the space in parallel with the rear surface plate, after being rotated by 90 degrees in the clockwise direction with reference to an arrangement state of the second substrate, the third substrate comprising:
• a first side extending along a part of the first portion, a second side extending along the second portion;
• a third side extending in parallel with the first side;
• and a fourth side extending in parallel with the second side;
• a fourth substrate arranged between the third portion and the fourth portion in the space in parallel with the rear surface plate, after being rotated by 90 degrees in the clockwise direction with reference to an arrangement state of the third substrate, the fourth substrate comprising:
• a first side extending along a part of the first portion, a second side extending along the second portion;
• a third side extending in parallel with the first side;
• and a fourth side extending in parallel with the second side;
• a fifth substrate arranged between the fourth portion and the first portion in the space in parallel with the rear surface plate, after being rotated by 90 degrees in the clockwise direction with reference to an arrangement state of the fourth substrate, the fifth substrate comprising:
• a first side extending along a part of the first portion, a second side extending along the second portion;
• a third side extending in parallel with the first side;
• and a fourth side extending in parallel with the second side;
• and
• a second wireless communication circuit electrically connected to the first antenna array and the second antenna array, configured to provide wireless communication in a second frequency band, and is attached to either (i) a first part on the third side closer to the fourth side than the second portion or (ii) a second part on the fourth side closer to the third side than the first portion.
