Electronic device including antenna

An electronic device comprising:

• a housing including a first plate, a second plate, and a side member surrounding an inner space of the electronic device between the first plate and the second plate;
• a ground layer spaced apart from the side member and disposed adjacent to at least a partial section of the side member;
• a display exposed through a portion of the first plate;
• a communication circuit disposed inside the housing;
• and a processor disposed inside the housing and electrically connected with the display and the communication circuit, wherein the side member includes a first conductive part, a second conductive part, and a non-conductive part in contact with the first conductive part and the second conductive part and interposed between the first conductive part and the second conductive part, wherein the first conductive part is electrically coupled with the second conductive part, wherein the ground layer is electrically coupled with a partial section of the first conductive part that is adjacent to the second conductive part, wherein the communication circuit is electrically connected with the first conductive part and the second conductive part, and
• wherein the second conductive part includes a first conductive protrusion adjacent to the non-conductive part and protruding toward the inner space of the electronic device and a second conductive protrusion protruding toward the inner space of the electronic device, wherein the first conductive protrusion is disposed between the first conductive part and the second conductive protrusion, and wherein the communication circuit is electrically connected with the second conductive protrusion of the second conductive part.
