An electronic device is disclosed. The electronic device includes a housing that includes a cover glass that exposes a portion of a display, and a rear housing. The rear housing includes a first conductive region, a second conductive region physically spaced from the first conductive region, and an insulating material interposed between the first conductive and the second conductive regions. The housing also includes a printed circuit board, a wireless communication circuit, a grip sensor circuit, and a connection member. The wireless communication circuit and the grip sensor circuit are electrically connected with the first conductive region. The connection member is interposed between the printed circuit board and the rear housing and electrically connects the first conductive region and the second conductive region. The wireless communication circuit is configured to feed the first conductive region; and transmit or receive a signal in a frequency band based on an electrical path.
