## Abstract

A test device with a built-in test antenna is provided. The test device is applicable to a device under test having an antenna under test. The test device with a built-in test antenna includes: a test base board, a test socket, and an antenna assembly. The test base board is electrically connected to a test apparatus. The test socket is disposed on the test base board. The device under test is to be disposed on the test socket. The antenna assembly includes a test antenna and an antenna board. The antenna assembly is disposed inside the test socket so as to be coupled to the test antenna. The antenna board is electrically connected to the test base board, and the position of the test antenna corresponds to that of the antenna under test.

## Claims

### Claim 1

A test device with a built-in test antenna for testing a device under test having an antenna under test, the test device comprising:
a test board electrically connected to a test apparatus;
a test socket disposed on the test board for carrying the device under test;
