    摘要: The embodiments described herein relate to anodic films and methods for forming anodic films. The methods described can be used to form anodic films that have a white appearance. Methods involve positioning reflective particles on or within a substrate prior to or during an anodizing process. The reflective particles are positioned within the metal oxide of the resultant anodic film but substantially outside the pores of the anodic film. The reflective particles scatter incident light giving the resultant anodic film a white appearance.

    摘要: 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.
