ANTENNA MODULE AND ELECTRONIC DEVICE COMPRISING SAME

An electronic device according to various embodiments of the present disclosure can comprise: a housing comprising a front plate which faces a first direction, a back plate which faces a second direction opposite from the first direction, and a lateral member which surrounds a space between the front plate and the back plate and has at least one part formed from a metal material; a display seen through a first part of the front plate; an antenna module positioned inside the space; and a wireless communication circuit which is electrically connected to the antenna module and is for transmitting and/or receiving a signal having a frequency of 20 GHz to 100 GHz. The antenna module can comprise: a first surface facing a third direction forming an acute angle with the second direction; a second surface facing a fourth direction opposite from the third direction; at least one first conductive element disposed on the first surface or inside the antenna module so as to face the third direction; and at least one second conductive element which is adjacent to the lateral member between the first surface and the second surface and extends in a fifth direction different from the third direction and the fourth direction and facing between the lateral surface and the first part of the front plate. Other embodiments are also possible.
