Abstract

A testing fixture used in an antenna testing process is provided. A cover unit having a second antenna portion is arranged on a base unit configured for an electronic structure having a first antenna portion to be placed thereon. The cover unit includes a non-metal interposing portion configured for pressing the electronic structure to separate the second antenna portion from the first antenna portion. Therefore, when the antenna testing process is performed on the electronic structure, a metal shielding effect is avoided, and an over the air testing environment is provided.

First claim

What is claimed is:

1. A testing fixture, comprising:
a base unit including a placing region for an electronic structure having a first antenna portion to be placed therein and a conductive portion arranged in the placing region and configured for being electrically connected to the electronic structure; and
a cover unit disposed on the base unit and including a second antenna portion associated with the first antenna portion in position and an interposing portion configured for separating the second antenna portion and the first antenna portion, the interposing portion being made of a non-metal material.

2. The testing fixture of claim 1 , wherein a dielectric constant of the interposing portion is within 1 to 3.2.

3. The testing fixture of claim 1 , wherein the cover unit has a concave portion corresponding to the electronic structure.

4. The testing fixture of claim 3 , wherein the concave portion of the interposing portion corresponds to the first antenna portion of the electronic structure in position.

5. The testing fixture of claim 1 , wherein the cover unit presses a whole top surface of the electronic structure.

6. The testing fixture of claim 1 , wherein the cover unit includes a plate body arranged with the second antenna portion and an interposing body bonded to the plate body and arranged with the interposing portion.

7. The testing fixture of claim 6 , wherein the plate body is bonded via an adhesive material to the interposing body.

8. The testing fixture of claim 1 , wherein the second antenna portion is in communicative connection with an external electronic device.

9. The testing fixture of claim 8 , wherein the cover unit further includes a switching element electrically connected to the second antenna portion, the second antenna portion is in communicative connection with the external electronic device via the switching element, and the switching element provides a signal transmission with a stable phase and a stable magnitude.

10. The testing fixture of claim 1 , further comprising an externally connectible member detachably disposed on the cover unit and configured for an environment member to be connected thereto externally.

11. The testing fixture of claim 1 , wherein a height of the interposing portion is associated with a width and a testing bandwidth of the electronic structure.

12. The testing fixture of claim 1 , wherein the cover unit is disposed on the base unit via a positioning structure, and a relative position between the cover unit and the base unit after being positioned is associated with a width and a testing bandwidth of the electronic structure.

13. The testing fixture of claim 1 , wherein the base unit includes:
a circuit board; and
a seat body disposed on the circuit board, arranged with the placing region and the conductive portion, and configured for the cover unit to be bonded thereto, and
wherein the conductive portion is elastically, electrically connected to the electronic structure and the circuit board.

14. The testing fixture of claim 13 , wherein the seat body is formed with a groove to act as the placing region, and the conductive portion is arranged in a bottom portion of the groove.

15. The testing fixture of claim 1 , wherein the conductive portion is a probe structure.
