Abstract

An apparatus for inspecting an antenna includes a stage including a ground on which an antenna device is disposed, an inspection board configured to be in contact with and connected to the antenna device, a connection maintaining unit for maintaining a contact and connection between the antenna device and the inspection board, and an inspection unit mounted or connected to the inspection board to inspect the antenna device.

First claim

What is claimed is:

1. An apparatus for inspecting an antenna, the apparatus comprising:
a stage on which an antenna device is disposed, the stage comprising a ground;
an inspection board configured to be in contact with and connected to the antenna device;
a connection maintaining unit for maintaining a contact and connection between the antenna device and the inspection board;
an inspection unit mounted or connected to the inspection board to inspect the antenna device; and
a first adjustment unit for determining an alignment state between the antenna device and the ground.

2. The apparatus for inspecting an antenna of claim 1 , wherein the ground is formed of a metal having a resistance value of 3 Ω or less.

3. The apparatus for inspecting an antenna of claim 2 , wherein the ground is formed of silver, gold, copper, aluminum or an alloy containing at least one therefrom.

4. The apparatus for inspecting an antenna of claim 1 , wherein the inspection board comprises a flexible printed circuit board.

5. The apparatus for inspecting an antenna of claim 1 , wherein the connection maintaining unit is configured to press a contact portion between the antenna device and the inspection board to maintain the contact and connection between the antenna device and the inspection board.

6. The apparatus for inspecting an antenna of claim 1 , wherein the inspection unit is configured to measures an S parameter and a radiation efficiency of the antenna device.

7. The apparatus for inspecting an antenna of claim 1 , wherein the first adjustment unit adjusts a position of the antenna device or the ground based on the determined alignment state.

8. The apparatus for inspecting an antenna of claim 1 , wherein the stage further comprises a board supporting portion, and the board supporting portion is configured to support the antenna device or the inspection board.

9. The apparatus for inspecting an antenna of claim 8 , wherein the board supporting portion is formed of Teflon or isopink.

10. An apparatus for inspecting an antenna, comprising:
a stage on which an antenna device is disposed, the stage comprising a ground;
an inspection board configured to be in contact with and connected to the antenna device;
a connection maintaining unit for maintaining a contact and connection between the antenna device and the inspection board;
an inspection unit mounted or connected to the inspection board to inspect the antenna device; and
a second adjustment unit for determining an alignment state or a contact state of the inspection board and the antenna device.

11. The apparatus for inspecting an antenna of claim 10 , wherein the second adjustment unit adjusts a position of the inspection board or the antenna device based on the determined alignment state or the contact state.

12. A method for inspecting an antenna, the method comprising:
placing an antenna device on a stage comprising a ground;
determining an alignment state between the antenna device and the ground;
adjusting a position of the antenna device or the ground based on the determined alignment state;
contacting and connecting an inspection board with the antenna device;
pressing a contact portion between the inspection board and the antenna device; and
inspecting the antenna device.

13. The method of claim 12 , further comprising:
determining an alignment state or a contact state between the inspection board and the antenna device; and
adjusting a position of the inspection board or the antenna device based on the determined alignment state or the contact state.
