1. An electronic device for forming a space between a front surface and a rear surface, the electronic device comprising:
a first cover disposed on the front surface;
a second cover disposed on the rear surface;
a frame enclosing the first cover and the second cover to form a side surface of the electronic device; and
a multilayer circuit board coupled to the second cover to constitute a housing of the electronic device,
wherein the multilayer circuit board comprises:
an insulated metal layer having one surface directly coupled to the second cover,
an antenna device of a substrate structure having one surface directly coupled to the insulated metal layer, and
a circuit board layer including a plurality of circuit boards coupled to the antenna device and configured to dispose at least one component at a surface opposite to a coupled surface of the antenna device,
wherein the insulated metal layer and the antenna device have the same length in a longitudinal direction,
wherein the circuit board layer has a longer length in a longitudinal direction than that of the antenna device,
wherein the circuit board layer comprises:
a first conductor coupled to one side in which the insulated metal layer, the antenna device, and the circuit board layer are aligned without a step in a longitudinal direction, and
a second conductor coupled on the insulated metal layer, a side surface of the antenna device, and the circuit board layer at the other side having a step,
wherein the at least one component is disposed at a surface opposite to a surface to which the second conductor is coupled on the circuit board layer, and
wherein the front surface is on the opposite side of the electronic device from the rear surface.
