Electronic device including antenna module

Abstract

A portable electronic device is provided. The portable electronic device includes a metal housing, an antenna module positioned in the metal housing, a first injection-molded member positioned in a radiation direction of the antenna module and having a first dielectric constant, a second injection-molded member at least partially in contact with the first injection-molded member, positioned in the radiation direction of the antenna module, and having a second dielectric constant different from the first dielectric constant, and a first organic film disposed along an inner surface of the metal housing to bond with at least a portion of the first injection-molded member, wherein the second injection-molded member forms, together with the metal housing, an exterior of the portable electronic device, and wherein the second injection-molded member is coupled with the first injection-molded member through a coupling structure in which one of the first injection-molded member or the second injection-molded member is at least partially protruding into another one of the first injection-molded member or the second injection-molded member.
