Test system of mobile phone antenna

Abstract

The invention discloses a test system of a mobile phone antenna. The test system comprises a test rotary table, a loudspeaker antenna, an integrative tester, a frequency spectrum tester, a signal distributor, a radiofrequency signal attenuator, a data acquisition apparatus and a display. The test rotary table and the loudspeaker antenna are positioned in a microwave darkroom. The integrative tester, the frequency spectrum tester, the signal distributor, the radiofrequency signal attenuator, the data acquisition apparatus and the display are positioned outside the microwave darkroom. A mobile phone is placed on the test rotary table and is connected with the signal distributor. The loudspeaker antenna and the integrative tester are connected with the frequency spectrum tester. The integrative tester is connected with the display through the data collector, and is connected with the signal distributor through the radiofrequency signal attenuator. The signal distributor is connected with the frequency spectrum tester. According to the invention, through forming a set of closed loop test system with the loudspeaker antenna, the integrative tester, the frequency spectrum tester, the radiofrequency signal attenuator and the signal distributor, influence of signal attenuation and radiation on a test is reduced, and a test result is accurate.

Description

technical field [0001] The invention relates to a testing technology for a mobile phone antenna, in particular to a testing system for a mobile phone antenna. Background technique [0002] Antenna testing is an indispensable link to ensure the stability of mobile phone radio frequency. A reasonable mobile phone antenna test device can not only accurately test various parameters that affect antenna performance, but also improve the performance, analyzability and radio frequency stability of the mobile phone radio frequency part . [0003] Such as figure 1 As shown in , it is a schematic structural diagram of a test system for an existing mobile phone antenna. As shown in the figure, it includes a mobile phone fixture 101, a test turntable 102, a horn antenna 103, a spectrum tester 104, a comprehensive tester 105, a data collector 106, a display 107 and some switching devices (not shown in the figure). The mobile phone fixture 101 is installed on the test turntable 102 for ...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned mobile phone antenna test system, since the spectrum tester is directly placed on the comprehensive tester, the interference between each device is relatively serious, which affects the test results of the corresponding parameters of the antenna

Moreover, in the above-mentioned test system, the distance between the test turntable and the horn antenna is relatively long, so that the RF test line between the horn antenna and the comprehensive tester is relatively long, which will cause signal attenuation and signal radiation interference, which further affects the mobile phone. The test parameters of the antenna, if the test results are inconsistent with the target results, it is necessary to repeat the test and improve the mobile phone antenna matching, which makes the test inefficient and also causes loss of test equipment
