Abstract

A housing includes a metal base and a non-conductive member. The metal base has an internal surface and a plurality of gap. The non-conductive member covers at least a portion of the internal surface of the metal base, and the non-conductive member is formed on the bottom of the at least one gap. The metal base is spaced by the gaps to form a plurality of metal sheets and at least one main body. Each gap is completely filled with one dielectric member. The metal sheets and the at least one main body are all bonded with the dielectric member and are electrically isolated with each other.

First claim

wherein the metal base is spaced by the gaps to form a plurality of metal sheets and at least one main body, each of the metal sheets is substantially U-shaped, each of the gaps is completely filled with a dielectric member, each of the dielectric member is substantially U-shaped, the metal sheets and the at least one main body are bonded with the dielectric member and are electrically isolated from with each other;
wherein the internal surface of the metal base is thinned to form a groove, a location of the groove corresponds to the plurality of the gaps, the nonconductive member is received in the groove.

2. The housing of claim 1 , wherein each of the gaps has a width of 0.02 mm to 0.7 mm along a direction from an adjacent one of the dielectric member located at one side of a corresponding one of the plurality of metal sheets to another adjacent one of the dielectric member located at an opposite side of the corresponding metal sheet;
each of the dielectric member has a width of 0.02 mm to 0.7 mm along a direction from an adjacent dielectric member located at one side of a corresponding one of the metal sheet to another adjacent one of the dielectric member located at an opposite side of the corresponding metal sheet.

3. The housing of claim 1 , wherein each of the metal sheet has a width of 0.15 mm to 1.0 mm along a direction from an adjacent one of the dielectric member located at one side of a corresponding one of the metal sheet to another adjacent one of the dielectric member located at an opposite side of the corresponding one of the metal sheet.

4. The housing of claim 1 , wherein the dielectric member is made of resin, rubber, or ceramic.

5. The housing of claim 1 , wherein the metal base is made of material selected from a group consisting of aluminum, aluminum alloy, magnesium, magnesium alloy, titanium, titanium alloy, copper and copper alloy.

6. The housing of claim 1 , wherein the non-conductive member is selected from a group consisting of polybutylene terephthalate, polyphenylene sulfide, polyethylene terephthalate, polyether ether ketone, polycarbonate, polyvinyl chloride polymer, polyurethane resin, epoxy, and polyurea resin.

7. The housing of claim 1 , wherein a length of each of the plurality of metal sheets is equal to a width of the housing.

8. The housing of claim 1 , wherein the non-conductive member is a U-shaped sheet.

9. The housing of claim 8 , wherein a width of the non-conductive member is larger than a total width of the plurality of metal sheets and the plurality of dielectric members.

10. An electronic device, comprising:
a body;

an antenna located inside the housing, the antenna corresponding to the at least one gap;
wherein the metal base is spaced by the gaps to form a plurality of metal sheets and at least one main body, each of the metal sheet is substantially U-shaped, each of the gaps is completely filled with a dielectric member, each of the dielectric member is substantially U-shaped, the metal sheets and the at least one main body are bonded with the dielectric member and are electrically isolated from each other;
wherein the internal surface of the metal base is thinned to form a groove, a location of the groove corresponds to the plurality of gaps, the non-conductive member is received in the groove.

11. The electronic device of claim 10 , wherein the metal base is a part of the antenna and couples with the antenna.

12. The housing of claim 1 , wherein each of the gaps has a width of 0.02 mm to 0.7 mm along a direction from an adjacent one of the dielectric member located at one side of a corresponding one of the plurality of metal sheets to another adjacent one of the dielectric member located at an opposite side of the corresponding metal sheet; and
each of the metal sheet has a width of 0.15 mm to 1.0 mm along a direction from an adjacent one of the dielectric member located at one side of a corresponding one of the metal sheet to another adjacent one of the dielectric member located at an opposite side of the corresponding one of the metal sheet.
