Abstract

Claims (24)

1. An electro-magnetic shield configured for placement within an enclosure for an electronic device that includes at least one wireless antenna, the shield comprising:

a metallic cage, the metallic cage including sides, a bottom and a top that collectively define an enclosed volume, the top being slanted at a non-zero angle with respect to the bottom;

a set of beveled through-holes defined in the top of the metallic cage, the set of beveled through-holes being aligned with respective structural posts of the enclosure, wherein the beveled through-holes are configured to enable assembly of the enclosure, and

at least one opening defined in the top of the metallic cage for passage of the at least one wireless antenna through the top of metallic cage.

2. The electro-magnetic shield of claim 1 , further comprising a front side and a rear side, at least one of the front and rear sides defining a cutout that is configured to accommodate an electrical connector.

3. The electro-magnetic shield of claim 1 , wherein the shield is further configured to receive at least a printed circuit board of the electronic device within the volume.

4. The electro-magnetic shield of claim 1 , further including a plurality of openings defined in the metallic cage, at least one of the openings being sized to enable the at least one wireless antenna or a conductor thereof to be inserted therethrough.

5. The electro-magnetic shield of claim 1 , wherein the set of beveled through holes are configured to conform to a shape of the respective structural posts of the enclosure.

6. The electro-magnetic shield of claim 5 , wherein each of the beveled through-holes of the set of beveled through-holes has a generally cross-shape.

7. The electro-magnetic shield of claim 1 , wherein each of the through-holes of the set of beveled through-holes is beveled to accommodate passage therethrough of a respective one of the structural posts of the enclosure, such that when the enclosure and the metallic cage are mated together, a longitudinal axis of each of the respective structural posts is not perpendicular with a plane defined by the top of the metallic cage.

8. An enclosure for an electronic device that includes a plurality of wireless antennas, the enclosure comprising:

a metallic cage, the metallic cage including sides, a bottom and a top that collectively define an enclosed volume, the top being slanted at a non-zero angle with respect to the bottom;

an outer enclosure at least partially enclosing the metallic cage, the enclosure defining a plurality of structural posts and a top surface that faces the top of the metallic cage, the top surface defining a plurality of recesses, each of the plurality of recesses being configured to receive a corresponding one of the plurality of wireless antennas of the electronic device, wherein the plurality of recesses are oriented to provide a predetermined angular displacement between the plurality of antennas;

a set of beveled through-holes defined in the top of the metallic cage, the set of beveled through-holes being aligned with respective ones of the structural posts.

9. The enclosure of claim 8 , wherein a plurality of openings are defined in the top of the metallic cage, each of the plurality of openings being configured for passage of one of the plurality of wireless antennas therethrough.

10. The enclosure of claim 8 , wherein the outer enclosure includes a top portion and a bottom portion and wherein each of the structural posts is configured to receive a screw to secure the top and bottom portions together.

11. The enclosure of claim 8 , wherein the outer enclosure includes a top portion and a bottom portion and wherein each of the structural posts is configured to snap-fit to secure the top and bottom portions together.

12. The enclosure of claim 8 , further comprising a front side and a rear side, at least one of the front and rear sides defining a cutout that is configured to accommodate an electrical connector.

13. The enclosure of claim 8 , wherein the shield is further configured to receive at least a printed circuit board of the electronic device within the enclosed volume.

14. The enclosure of claim 8 , further including a plurality of openings defined in the metallic cage, at least some of the openings being sized to accommodate one of the plurality of antennas therethrough.

15. The enclosure of claim 8 , wherein the set of beveled through holes are configured to conform to a shape of the respective structural posts of the enclosure.

16. The enclosure of claim 15 , wherein each of the beveled through-holes of the set of beveled through-holes has a generally cross-shape.

17. The enclosure of claim 8 , wherein each of the through-holes of the set of beveled through-holes is beveled to accommodate passage therethrough of a respective one of the structural posts of the enclosure, such that when the enclosure and the metallic cage are mated together, a longitudinal axis of each of the respective structural posts is not perpendicular with a plane defined by the top of the metallic cage.

18. The enclosure of claim 8 , wherein the outer enclosure and the plurality of recesses defined therein are configured to define a spacing between the antennas received in the recesses and the metallic cage that is sufficient so as to not substantially degrade a performance of the plurality of antennas.
