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.

First claim

What is claimed is:

1 . 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 is configured in such a manner that it provides electrical decoupling of the feed of the antenna radiators from one another.

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 that it can 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 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.

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

7 . 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.

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

9 . The shield housing according to claim 1 , wherein the shield housing consists of two parts, which can be disposed on the circuit board at a predetermined shield housing distance from one another.

10 . The shield housing according to claim 1 , wherein the shield housing has pins for contacting the ground surface of the circuit board on its outer edge, which pins are disposed at a predetermined pin distance from one another.

11 . The shield housing according to claim 6 , wherein the predetermined pin distance amounts to between 5 mm to 15 mm, inclusive.

12 . The shield housing according to claim 1 , wherein the shield housing has recesses for placement of the two antenna radiators, wherein the shield housing has a structure that is deep-drawn from it, having at least one pin disposed on it for contacting the ground surface of the circuit board in the region in which the inner conductor of each antenna radiator is connected with the circuit board.

13 . A connection element for connecting an antenna radiator disposed on the shield housing according to claim 1 with the ground surface of the circuit board, wherein the shield housing has recesses for placement of the antenna radiator and wherein the connection element is configured in such a manner that it can be disposed in the region in which the inner conductor of each antenna radiator is connected with the circuit board.

14 . The connection element according to claim 13 , wherein the connection element is coupled with the shield housing capacitively or galvanically and has structures by means of which the shortest possible connection between the line system of the antenna radiator and the ground surface of the circuit board can be provided.

15 . An antenna radiator for placement on a shield housing according to claim 1 , wherein the antenna radiator has an extension of its line system and at least one pin, so as to be contacted with the ground surface of the circuit board.

16 . A system, comprising
a shield housing and/or a connection element and/or an antenna radiator according to claim 1 , which housing or element or radiator is or are disposed on a circuit board,
wherein the circuit board has recesses for passing through all the pins and structures to be contacted with the circuit board, and
an adapter plate, which is disposed on the side of the circuit board that lies opposite the shield housing, and a reflector disposed on the adapter plate, wherein the adapter plate is configured in such a manner that it bulges outward at locations where a pin is passed through the circuit board to the side of the adapter plate, above the pin, and the reflector has an opening at this location.

17 . A system, comprising
a shield housing and/or a connection element and/or an antenna radiator according to claim 1 , which system or element or radiator is or are disposed on a circuit board,
wherein the circuit board has recesses for passing through all the pins and structures to be contacted with the circuit board, and
an adapter plate, which is disposed on the side of the circuit board that lies opposite the shield housing, and a reflector disposed on the adapter plate, wherein the adapter plate is configured in such a manner that it has a minimum thickness that corresponds to a length of the longest pin passed through the circuit board to the side of the adapter plate, and has an opening at locations where a pin is passed through the circuit board to the side of the adapter plate.
