Abstract: An electronic device is provided. The electronic device includes a housing including a conductive portion, the conductive portion including a first segment and a second segment separated from the first segment by a first gap, a first switch configured to selectively connect the first segment and the second segment, a first wireless communication circuit including a first port and a second port, the first port being electrically connected to the first segment, and a second switch configured to selectively connect the second port and the second segment, wherein the first wireless communication circuit is configured to operate in a first mode or a second mode, wherein the first mode is configured to transmit and/or receive a wireless signal in a first frequency range by using a first antenna formed from the first segment electrically open to the second segment through the first switch, and transmit and/or receive the wireless signal in the first frequency range by using a second antenna formed from the second segment electrically open to the first segment through the first switch and electrically connected to the second port through the second switch, wherein the second mode is configured to transmit and/or receive a wireless signal in the first frequency range and a second frequency range by using a third antenna formed from the first segment electrically connected to the second segment through the first switch and the second segment electrically open to the second port through the second switch, and wherein the second frequency range is different from the first frequency range.
