Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

The present disclosure is mainly applied to a terminal that transmits and receives signals using an antenna, such as a mobile phone. In the related art, when the radiation performance of an antenna of a terminal is tested, the terminal needs to be disassembled, a test line is welded between an RF PA for generating a radio frequency signal in the terminal and the antenna, and the terminal can be tested through the test line after being installed. It can be seen that the operation is complicated when the radiation performance of the antenna of the terminal is tested. Moreover, such complicated operations are further problematic in certain scenarios. For example, when The terminal performs an Over The Air (OTA) test (The OTA test belongs to an active test), since passive data of an antenna of The terminal cannot be checked, such as a return loss S11, a directional diagram, and The like, when a deviation of an OTA test result is large, a specific reason cannot be determined. For another example, in the background of increasing numbers of terminals currently using metal housings as antennas, the terminals may be detached once to cause variations in antenna performance. Furthermore, in the process of after-sale maintenance of the terminal by after-sale personnel, whether the signal of the terminal is affected by the dismounting action is difficult to ensure, and then the problem that the signal cannot be correlated is caused.
Fig. 1 is a schematic diagram illustrating a structure of a terminal according to an exemplary embodiment. As shown in fig. 1, the terminal 10 of the present embodiment may include: a chassis (not shown), an antenna body 11, a Radio Frequency (RF) Power Amplifier (PA) 12, and an antenna test module 13; the antenna test module 13 includes: a first test interface 131 and a first selection submodule 132; a first notch matched with the first test interface 131 is formed in the shell, and the first test interface 131 is located in the first notch; a first test interface 131 for providing an interface for testing the antenna body 11; the first selecting submodule 132 is connected to the output end of the rf power amplifier 12, the first testing interface 131 and the antenna body 11, respectively, and is configured to select the first testing interface 131 to be connected to the antenna body 11, or select the output end of the rf power amplifier 12 to be connected to the antenna body 11.
Specifically, when the radiation performance of the antenna body 11 needs to be tested (that is, a passive test needs to be performed), the first selection sub-module 132 selects the first test interface 131 to connect with the antenna body 11, and further, the antenna body of the terminal can be tested through the first test interface provided by the antenna test module 13. When the radiation performance of the antenna does not need to be tested (for example, active test is needed), the output end of the rf power amplifier 12 is selected by the first selection sub-module 132 to be connected to the antenna body. Because the first testing interface 131 can be selected to be connected with the antenna body 11 through the first selection sub-module 132, or the output end of the radio frequency power amplifier 12 is selected to be connected with the antenna body 11, and the antenna body 11 is tested through the first testing interface 131 located in the first gap of the housing, a tester can test the antenna body through the first testing interface without disassembling the terminal.

When the active test of the terminal is required, the first selection submodule 132 is controlled to be in the second state, so that the first connection interface B1 is connected with the third connection interface B3, and the output terminal of the RF PA12 is connected with the antenna body 11 through the first connection interface B1 and the third connection interface B3. Because the first testing interface 131 can be controlled to be connected with the antenna body 11 and the output end of the radio frequency power amplifier is controlled to be disconnected with the antenna body 11 by controlling the state of the first selection submodule 14, or the first testing interface 131 can be controlled to be disconnected with the antenna body 11 and the output end of the radio frequency power amplifier is controlled to be connected with the antenna body 11, and the antenna body 11 is tested by the first testing interface 131 located in the first notch of the case under the condition that the first testing interface 131 is connected with the antenna body 11 and the output end of the radio frequency power amplifier is disconnected with the antenna body 11, the tester can complete the switching between the active test of the terminal and the passive test of the antenna of the terminal by controlling the state of the first selection submodule, thereby avoiding the disassembly of the terminal.
