Arrangement structure for communication device and electronic device including the same

A portable communication device comprising:

• a housing comprising:
• a front surface plate;
• a rear surface plate facing toward an opposite direction of the front surface plate;
• and
• a conductive side surface member substantially surrounding a space between the front surface plate and the rear surface plate, the conductive side surface member including a hole portion, the hole portion substantially filled with a non-conductive material;
• a communication processor disposed on a first substrate accommodated in the housing;
• and
• a first communication device comprising a second substrate and a first antenna array disposed on the second substrate,
• wherein the first antenna array is adjacent to and substantially parallel with an inner surface of the hole portion formed in the conductive side surface member, and
• wherein the first antenna array is disposed to face the hole portion and is configured to radiate at least part of a beam of radio frequency (RF) signals in a direction toward the hole portion based on a control by the communication processor.
