Electronic apparatus comprising antenna

An electronic device comprising:

• a housing comprising a first part, a second part, and a connecting portion disposed between the first part and the second part, wherein the second part is rotatably coupled to the first part via the connecting portion;
• a flexible display forming at least a portion of a front surface of the electronic device in a state in which the housing is unfolded, wherein the flexible display is disposed over the first part and the second part;
• a key button disposed in a first area of a side surface of the first part, wherein the key button comprises at least one protrusion extending toward inside of the first part;
• and
• an antenna structure disposed in the inside of the first part with respect to the first area,
• wherein the antenna structure comprises:
• a substrate comprising multiple layers including a conductive layer and a non-conductive layer;
• at least one dome switch disposed on the substrate at a position corresponding to the at least one protrusion;
• and
• a plurality of conductive patches provided in the conductive layer of the substrate, and
• wherein the at least one dome switch is disposed at a position corresponding to a space between the plurality of conductive patches.
