[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
