Abstract
A housing for an electronic device, including an aluminum layer enclosing a volume that includes a radio-frequency (RF) antenna is provided. The housing includes a window aligned with the RF antenna; the window including a non-conductive material filling a cavity in the aluminum layer; and a thin aluminum oxide layer adjacent to the aluminum layer and to the non-conductive material; wherein the non-conductive material and the thin aluminum oxide layer form an RF-transparent path through the window. A housing for an electronic device including an integrated RF-antenna is also provided. A method of manufacturing a housing for an electronic device as described above is provided.
