    Abstract: A housing for a portable electronic device includes a radio frequency transparent polycrystalline ceramic portion comprising a first surface and a second surface parallel to the first surface. The radio frequency transparent polycrystalline ceramic portion comprises a macro-texture on at least a portion of the first surface, and a predetermined micro-texture is disposed on at least a portion of the macro-texture. A method for manufacturing a housing for a portable electronic device includes forming a green ceramic article comprising a first surface and a second surface parallel to the first surface, embossing at least a portion of the first surface of the green ceramic article with a macro-texture, and sintering the green ceramic article comprising the macro-texture to form a sintered ceramic article. A predetermined micro-texture is disposed on at least a portion of the macro-texture.
