Apparatus and method for arranging antennas supporting millimeter wave frequency bands

An electronic device comprising:

• a housing including a first plate forming at least a portion of a front surface of the electronic device, a second plate facing away from the first plate and forming at least a portion of a back surface of the electronic device, and a side member at least partially surrounding a space between the first plate and the second plate;
• a display positioned within the housing, and visually exposed outside the electronic device through a portion of the first plate;
• an antenna structure positioned within the housing, wherein the antenna structure includes:
• at least one first conductive plate facing a first direction, the first direction facing the second plate, and at least one first dipole formed between the first conductive plate and a first portion of the side member, when viewed from above the second plate;
• at least one second conductive plate facing a second direction, the second direction facing the side member, while electrically connected to the at least one first conductive plate, at least one second dipole antenna formed between the second conductive plate and the second plate, when viewed from above the side member, and
• at least one radio frequency integrated circuit (RFIC) electrically connected with the at least one first conductive plate, the at least one first dipole antenna, the at least one second conductive plate, and the at least one second dipole antenna, and configured to transmit/receive a signal having a frequency between 3 GHz and 100 GHz.
