Electronic device having a housing with embedded antenna

Electronic device having at least one main antenna wherein such antenna is formed as a conductive layer on walls of a housing of the electronic device, said conductive layer comprising a deposited copper layer on said walls and has a first portion on an internal part of the housing, a second portion forming a first junction area on an edge between an interior part and an exterior part of the housing, a third portion on an outer part of the housing in electrical continuity with the first portion through the first junction area and a second junction area connecting said third portion to connecting tracks inside said housing and wherein the first portion comprises a first flat area on a first wall of the housing, a second flat area on a second wall of the housing perpendicular to the first wall so that said first flat area and second flat area are perpendicular, said main antenna being folded at an inner junction between said first flat area and said second flat area, and wherein the housing houses at least one PCB and wherein the first wall on which the first flat area is located is a bottom wall of the housing parallel to the PCB, and wherein the second wall on which the second flat area is located is a sidewall of the housing perpendicular to the bottom wall, said second flat area being perpendicular to the PCB inside the housing and parallel to the third portion outside the housing.
