Abstract: Various embodiments of the present invention relate to an electronic device comprising a wireless communication circuit, and a portable communication device. An electronic device, according to one embodiment, comprises: a housing including a side member that forms the sides of the electronic device; a touchscreen display which is at least partially housed in the housing so as to be visually exposed to the outside; a first conductive portion formed from a first portion of the side member; a second conductive portion formed from a second portion of the side member, opposite to the first portion when viewed from the top of the touch screen display exposed to the outside; and at least one wireless communication circuit electrically connected to a first point within the first portion and a second point within the second portion, wherein the at least one wireless communication circuit can be configured to support transmit diversity by generating a first signal having a first phase of a primary configuration carrier and a second signal having a second phase of the primary configuration carrier, transmitting the first signal through the first conductive portion, and transmitting the second signal through the second conductive portion. Other various embodiments are possible.
