MOBILE COMMUNICATION DEVICE COMPRISING ANTENNA

A mobile communication device according to an embodiment may comprise: a housing which includes a first edge and a second edge of the mobile communication device, the first edge extending in a first direction and the second edge extending from one end of the first edge in a second direction perpendicular to the first direction; a wireless communication circuit which is disposed in the housing; and a conductive member which forms a part of the housing or is disposed in the housing, wherein: the housing includes a first conductive portion forming a part of the first edge and having a predetermined length, and a second conductive portion forming an inner frame of the mobile communication device; the first conductive portion includes a protrusion extending from a first point of the first edge, a first portion extending a first length from the first point in the first direction, and a second portion extending a second length greater than the first length from the first point in the opposite direction to the first direction; at least a part of the second conductive portion is spaced apart from the first conductive portion in the second direction and formed parallel to the first conductive portion, and includes an indentation formed to correspond to the protrusion of the first conductive portion; the conductive member is disposed between the second portion of the first conductive portion, the second conductive portion, and the protrusion; and the wireless communication circuit supplies power to the protrusion to transmit/receive a wireless signal through the first conductive portion, the second conductive portion, or at least a part of the conductive member. Various other embodiments may also be disclosed.
