Production detection system used for mobile terminal antenna

Abstract

The invention discloses a production detection system for a mobile terminal antenna, comprising a network analyzer and further comprising a test dark box and a computer for computation and output in cooperation with the network analyzer, a reception antenna clamp and a transmission antenna clamp are provided in the test dark box; the reception antenna clamp is connected with a S21 port of the network analyzer via a coaxial cable; the transmission antenna clamp is connected with a S11 port of the network analyzer via the coaxial cable; the transmission antenna clamp comprises a cylinder and a clamp body, the cylinder is provided with a travel switch thereon which is connected via a travel switch signal line to a printer interface of the computer. The invention can measure S11 and S21 parameters of the measured antenna simultaneously, wherein, the S21 reflects the gains of the antenna and the S11 reflects the matching performance of the antenna, and can comprehensively measure performance of the antenna to guarantee that the measured antenna reaches the setting standard.

Description

Technical field: [0001] The invention relates to a production testing system for mobile terminal antennas, which belongs to the technical field of wireless communication equipment production, in particular to a production testing system for mobile terminal antennas. Background technique: [0002] The production inspection of mobile terminal antennas is very important. If the antenna components are defective, the RF performance of the whole machine assembly will be reduced. The resulting rework will increase production costs and reduce production efficiency. For the production line detection of mobile terminal antennas, the traditional method is to use a network analyzer to measure S11 (or VSWR, return loss, these indicators reflect the same physical concept, and the VSWR indicator will be used to describe below) , the purpose is to check the consistency (such as detecting the distribution of the S11 amplitude at a certain frequency point). This indicator reflects the matchi...

Problems solved by technology

Although the above-mentioned technical scheme also adopts a network analyzer as the main test equipment, the antenna under test of the test system is not easy to fix, and the operation is inconvenient, which affects the effect of the test. In addition, there will be reflection of electromagnetic waves during the test. It will also affect the effect of the test, and such a test method can only test one parameter, check consistency, and cannot measure other required parameters
