Abstract

The present disclosure provides an electronic product metal shell with an antenna groove and a method of manufacturing the same. The electronic product metal shell includes a metal layer, a hard anodic oxidation layer, a step recess, an antenna groove and a non-conductive material filled in the antenna groove. The metal layer may have a first surface and a second surface. The hard anodic oxidation layer may be coated on the first surface and the second surface of the metal layer. The step recess may be formed through the hard anodic oxidation layer on the first surface of the metal layer and partially into the metal layer. The antenna groove may be formed within the step recess extending through the metal layer to expose an inner side of the hard anodic oxidation layer on the second surface of the metal layer.
