An electronic device includes a housing configured to form an internal space, a radiating sheet configured to be disposed in the internal space; at least one electronic component configured to be disposed in the internal space and to be in contact with the radiating sheet. An FPCB antenna module configured to be disposed on the radiating sheet includes a conductive pattern and a nonconductive layer configured to surround the conductive pattern, wherein the nonconductive layer may extend on the radiating sheet to a region in which the electronic component is positioned.
