An automated antenna testing device is disclosed. A carrying stand for objects-to-be-tested to be carried thereon, and an antenna stand corresponding to the carrying stand are installed in a receiving space of a cavity part on a machine part, and a conveyance device for moving the objects-to-be-tested to the carrying stand is installed on the machine part. The conveyance device and the cavity part are installed independently, therefore, an OTA testing environment can be prevented from being affected by external factors.
