Abstract

A system for contactless testing of radio frequency apertures is provided. The system comprises a fixture having a fixture mount operable to be received in a fixture receiver of a robotic system, and a vector network analyzer (“VNA”) supported by the fixture. A radiating antenna is supported by the fixture, and is operable to be connected to the VNA via a cable. Upon movement of the fixture via the robotic system, the VNA, the radiating antenna, and the cable maintain a static positional relationship relative to one another.

Claims (51)

1. A system for contactless testing of radio frequency apertures, the system comprising:

a fixture comprising a fixture mount configured to be received in a fixture receiver of a robotic system;

a network analyzer supported by the fixture; and

a radiating antenna supported by the fixture, the radiating antenna connected to the network analyzer via at least one cable;

wherein, upon movement of the fixture via the robotic system, the network analyzer, the radiating antenna, and the at least one cable maintain a static positional relationship relative to one another.

2. The system of claim 1 , wherein:

the fixture further comprises a housing; and

the fixture mount is disposed on a top side of the housing.

3. The system of claim 2 , wherein the network analyzer is disposed at least partially within the housing.

4. The system of claim 3 , wherein:

the housing has an open side; and

the at least one cable is connected to the network analyzer at the open side.

5. The system of claim 2 , wherein the radiating antenna is disposed on a lower side of the housing.

6. The system of claim 1 , wherein the radiating antenna comprises a horn antenna.

7. A system for integrated manufacturing and testing of radio frequency apertures, the system comprising:

a robotic arm comprising a fixture receiver supported at a distal end of the robotic arm;

a contact probe comprising a first fixture mount configured to be received by the fixture receiver of the robotic arm, the contact probe configured to contact test traces of one or more printed wire boards;

a soldering tip comprising a second fixture mount configured to be received by the fixture receiver of the robotic arm, the soldering tip configured to join the printed wire boards and other components of the radio frequency apertures; and

a contactless probe comprising:

a fixture comprising a third fixture mount configured to be received by the fixture receiver of the robotic arm;

a network analyzer supported by the fixture; and

a radiating antenna supported by the fixture, the radiating antenna connected to the network analyzer via at least one cable;

wherein, upon movement of the fixture via the robotic arm, the network analyzer, the radiating antenna, and the at least one cable maintain a static positional relationship relative to one another; and

wherein the contactless probe being operable is configured to validate functionality of the radio frequency apertures.

8. The system of claim 7 , wherein the robotic arm comprises a six-axis robotic arm.

9. The system of claim 7 , wherein the contactless probe further comprises a housing supporting the third fixture mount, the network analyzer, and the radiating antenna.

10. The system of claim 9 , wherein the housing comprises a top frame, a bottom frame, and side frames connecting the top frame to the bottom frame to define an internal compartment.

11. The system of claim 10 , wherein the network analyzer is disposed at least partially within the internal compartment.

12. The system of claim 10 , wherein:

the third fixture mount is disposed on the top frame; and

the radiating antenna is supported by the bottom frame.

13. The system of claim 10 , wherein:

the housing comprises an open side; and

the network analyzer comprises one or more cable connection points that are disposed at the open side.

14. The system of claim 7 , wherein the radiating antenna comprises a horn antenna.

15. The system of claim 7 , wherein the fixture receiver comprises a quick connect type mount.

16. A method for integrated testing and manufacturing of radio frequency apertures, the method comprising:

operating a contact probe with a robotic arm to evaluate functionality of traces on a printed wire board;

operating a soldering tip with the robotic arm to solder the printed wire board to one or more other components to form a radio frequency apertures assembly; and

operating a contactless probe with the robotic arm to evaluate functionality of the radio frequency apertures using the contactless probe;

wherein the contactless probe comprises:

a fixture comprising a fixture mount configured to be received in a fixture receiver of the robotic arm;

a network analyzer supported by the fixture; and

a radiating antenna supported by the fixture, the radiating antenna connected to the network analyzer via at least one cable; and

wherein, upon movement of the fixture via the robotic arm, the network analyzer, the radiating antenna, and the at least one cable maintain a static positional relationship relative to one another.

17. The method of claim 16 , wherein operating the contactless probe comprises moving a the network analyzer and the radiating antenna supported by a housing attached to the robotic arm.

18. The method of claim 17 , wherein the network analyzer is disposed at least partially within the housing.

19. The method of claim 16 , further comprising:

removing the contact probe from the robotic arm after operating the contact probe and attaching the soldering tip to the robotic arm.

20. The method of claim 19 , further comprising:

removing the soldering tip from the robotic arm after operating the soldering tip and attaching the contactless probe to the robotic arm.
