Problems solved by technology

[0002] With the rapid development of science and technology, handheld mobile terminals such as PAD, smart phones, etc. Most of them use the built-in mobile terminal antenna, and before using the mobile terminal antenna, it is necessary to test the radio frequency parameters of the mobile terminal antenna to check whether it meets the factory requirements. The entire testing process needs to be in a sealed resonant cavity. The detection base of the terminal antenna is engaged with the resonant cavity to form a sealed state. The probe set on the detection base is used to detect the radio frequency parameters, and the network analyzer is connected to the network analyzer through the wires to analyze the radio frequency parameters. However, due to the use of external wires, There will be large electromagnetic interference between the wires, which will affect the accuracy of radio frequency parameter detection, and the existing mobile terminal antenna is not fixed on the detection base with any fixing measures, which will cause displacement during the detection process and will also affect the The accuracy of radio frequency parameter detection will affect

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a detection base of a mobile terminal antenna includes a substrate 1, a PWB board 2 and a backing board 3, the PWB board 2 is a commonly used printed circuit board, and the PWB board 2 is fixed on the top of the substrate 1 through the backing board 3. The board 2 is provided with a probe 4 for detecting the radio frequency parameters of the mobile terminal antenna. The probe 4 is located at the detection point of the mobile terminal antenna. The interface 6 is connected, and the SMA interface 6 is used to connect an external network analyzer. Here, the radio frequency parameter signal is transmitted through the wire printed in the PWB board 2. Compared with the traditional wire transmission, the electromagnetic interference is greatly reduced and the detection accuracy is improved. On the PWB board 2 There is a positioning post 5 for po...
