Abstract

What is provided is a shield housing for shielding interconnect structures and/or components disposed on a circuit board, wherein at least two antenna radiators can be disposed on the shield housing, and wherein the shield housing is configured in such a manner that it can cover the interconnect structures and/or components disposed on the circuit board, at least in part, can be connected with a ground surface of the circuit board, and has a region between the antenna radiators, which region is configured in such a manner that it provides electrical decoupling of the feed of the antenna radiators from one another.

Claims

1. A shield housing for shielding interconnect structures and/or components disposed on a circuit board, wherein at least two antenna radiators are disposed on the shield housing, wherein the shield housing, is configured in such a manner cover the interconnect structures and/or components disposed on the circuit board, at least in part, to be connected with a ground surface of the circuit board, and wherein the shield housing has a region between the antenna radiators, which is configured in such a manner to provide electrical decoupling of a feed of the antenna radiators from one another wherein the region between the antenna radiators is a region in the center of the shield housing, which region is configured as an opening having folded areas around the opening in the shield housing.

2. The shield housing according to claim 1, wherein the shield housing is configured in one piece.

3. The shield housing according to claim 1, wherein the shield housing is configured in such a manner to completely cover the interconnect structures and/or components disposed on the circuit board.

4. The shield housing according to claim 1, wherein a ground is drawn to the ground surface of the circuit board on the top of the circuit board by means of through-contacting, and the shield housing is contacted with the ground directly on the top.

5. The shield housing according to claim 1, wherein pins, which are disposed at a predetermined pin distance from one another, are disposed at the folded areas for contacting the circuit board.

6. The shield housing according to claim 1, wherein the region between the feeds of the antenna radiators is configured as a partition wall connected with the shield housing.

7. The shield housing according to claim 6, wherein the partition wall is electrically connected or coupled with the shield housing, capacitively or galvanically.

8. The shield housing according to claim 1, wherein the shield housing has pins for contacting the ground surface of the circuit board on Ps—

the outer edge of the circuit board, which pins are disposed at a predetermined distance from one another.

9. The shield housing according to claim 5, wherein the predetermined distance of the protrusions amounts to between 5 mm to 15 mm, inclusive.
