Abstract: A patch for a device in an electronic housing including an aluminum layer having a threshold thickness, a non-conductive layer on a first side of the aluminum layer, and a radio-frequency (RF) transparent layer on a second side of the aluminum layer is provided. A method for manufacturing an antenna window including a patch as above is also provided, the method including determining a thickness of the aluminum layer adjacent to an anodized aluminum layer. A method for manufacturing an antenna window including coating an aluminum layer having a threshold thickness on a radio-frequency (RF) transparent layer to form an RF transparent laminate is also provided. A method for manufacturing an antenna window including removing a thickness of aluminum is also provided. A method for manufacturing an antenna window including disposing a mask on an aluminum substrate and anodizing the aluminum substrate to a selected thickness is also provided.
