Abstract

The present invention relates to a substrate for supporting an antenna pattern. The substrate includes a porous anodic oxide layer having a plurality of pores formed by anodizing metal. A metallic material is filled in at least a part of the pores.

Claims

1. A substrate for supporting an antenna pattern, comprising a porous anodic oxide layer having a plurality of pores formed by anodizing metal, wherein a metallic material is filled in at least a part of the pores.

2. The substrate of claim 1, wherein the porous anodic oxide layer is a porous aluminum oxide layer formed by anodizing aluminum.

4. The substrate of claim 1, wherein the metallic material includes at least one of a carbon nanotube, graphene, nickel (Ni), silver (Ag), gold (Au), copper (Cu), platinum (Pt), titanium-tungsten alloy (TiW), chromium (Cr) and nickel-chromium alloy (NiCr).

5. The substrate of claim 1, wherein the pores include pores filled with the metallic material and pores not filled with the metallic material.

7. The substrate of claim 1, wherein each of the pores is only partially filled with the metallic material.

11. The antenna of claim 10, further comprising a metal base plate

wherein the metal base plate is anodized to form the plurality of pores.

12. The antenna of claim 10, wherein the metallic material is filled in the pores positioned below the metal pattern.

13. The antenna of claim 10, wherein the metallic material is filled in the pores spaced apart from the metal pattern.

14. The antenna of claim 10, wherein the metal pattern includes a first metal pattern and a second metal pattern formed outside the first metal pattern so as to surround at least a part of the first metal pattern.

16. The antenna of claim 11, wherein the metal base plate has an opening portion.

18. The antenna of claim 10, further comprising:

an insulating material layer formed on at least a portion of the porous anodic oxide layer, on at least a portion of the metal pattern, or on at least a portion of the porous anodic oxide layer and the metal pattern.

20. The antenna of claim 10, wherein an outer surface of the metallic material is exposed below the porous anodic oxide layer.

21. The antenna of claim 20, further comprising:

a lower metal layer formed on at least a part of a lower portion of the porous anodic oxide layer.

22. The antenna of claim 10, wherein the porous anodic oxide layer comprises aluminum oxide.
