Abstract

An electronic device is provided, which includes an FPCB, wherein the FPCB includes a first portion in which an antenna is provided in the form of a patch antenna that overlaps a metal member, a second portion coupled to a connector of the circuit board, and a third portion arranged between the first portion and the second portion. A layered structure of the FPCB may include a dielectric material having a first thickness in the first portion overlapping the metal member and having a second thickness smaller than the first thickness in the second portion and the third portion, a first conductive layer provided in the first direction from the dielectric material, and an intermediate conductive layer provided in a second direction opposite to the first direction, from the dielectric material. The intermediate conductive layer may be provided only in the second portion and the third portion and may not be provided in the first portion. A portion of the dielectric material in the first portion can be arranged to face the metal member.
