Abstract

A housing, a method for manufacturing an antenna, and a mobile terminal having the housing are provided. The housing includes a substrate at least including a metal area, a slot defined in the metal area of the substrate and penetrating through the substrate, and a filling layer received in the slot and including an insulating layer and a paint layer on the insulating layer. The paint layer has a width which is 0.02-0.06 mm larger than that of the insulating layer. An outer surface of the paint layer and an outer surface of the substrate have a same color.

First claim

What is claimed is:

1. A housing, comprising:
a substrate at least comprising a metal area;
a slot defined in the metal area of the substrate and penetrating through the substrate;
a filling layer received in the slot and comprising an insulating layer and a paint layer on the insulating layer;
the paint layer having a width which is 0.02-0.06 mm larger than that of the insulating layer; and
an outer surface of the paint layer having a same color as an outer surface of the substrate.

2. The housing of claim 1 , wherein the paint layer has a thickness of 0.2-0.3 mm.

3. The housing of claim 1 , wherein the paint layer comprises:
a base paint layer;
a colored paint layer being disposed on an outer surface of the base paint layer; and
a top paint layer being disposed on an outer surface of the colored paint layer.

4. The housing of claim 1 , wherein the exterior of the filling layer is the paint layer.

5. The housing of claim 3 , wherein the colored paint layer has a same color as the outer surface of the substrate.

6. The housing of claim 3 , wherein at least one of the group consisting of the base paint layer, the colored paint layer, and the top paint layer comprises at least one sub-layer.

7. A mobile terminal, comprising a housing, wherein the housing comprises:
a substrate at least comprising a metal area;
a slot defined in the metal area of the substrate and penetrating through the substrate;
a filling layer received in the slot and comprising an insulating layer and a paint layer on the insulating layer;
the paint layer having a width which is 0.02-0.06 mm larger than that of the insulating layer; and
an outer surface of the paint layer having a same color as an outer surface of the substrate.

8. The mobile terminal of claim 7 , wherein the paint layer has a thickness of 0.2-0.3 mm.

9. The mobile terminal of claim 7 , wherein the paint layer comprises:
a base paint layer;
a colored paint layer being disposed on an outer surface of the base paint layer; and
a top paint layer being disposed on an outer surface of the colored paint layer.
