Handset antenna test method and system

Abstract

The invention discloses a handset antenna test system and method. The system includes a shielding box; a clamp arranged in the shielding box and used for fixing a handset; a test antenna which is arranged in the shielding box and provided with a plurality of test frequency bands and corresponding to the handset clamp in position; a test instrument which is arranged outside the shielding box and connected with the test antenna; and a computer which is connected with the test instrument and the handset and used for controlling the handset and the test instrument. Because the cost of different parts used in the handset antenna system is comparatively low, test cost is reduced. Moreover, compared with the prior quadrihedron shielding box, the shielding box is not only capable of shielding interferences from the outside and improving test precision, but also convenient to install. Moreover, the test antenna is provided with the plurality of test frequency bands so that tests of all handset antennae can be covered.

Description

technical field [0001] The invention relates to the technical field of mobile phone antenna testing, and more specifically, to a method and system for quickly testing mobile phone antennas. Background technique [0002] Usually, the active test of mobile phone antenna needs to be carried out in a professional laboratory, and requires a long test time. Due to the high cost and long test time, it is only suitable for R&D or sampling test, not suitable for factory production Assembly inspection. [0003] Currently, there are two methods for testing the performance of mobile phone antennas during production line assembly. One is the method of using the coupling plate, and the other is the method of using the standard triangular cone shielding box. [0004] When using the coupling board method for testing, since the mobile phone to be tested is directly placed above the coupling board, the coupling board interferes a lot with the performance of the mobile phone antenna; moreove...

AI Technical Summary

Problems solved by technology

[0004] When using the coupling board method for testing, since the mobile phone to be tested is directly placed above the coupling board, the coupling board interferes a lot with the performance of the mobile phone antenna; moreover, the test is carried out in an open environment, and the external interference cannot be eliminated. Therefore, the test accuracy of this method is low, and it is greatly affected by the environment.

[0005] When using the standard triangular cone shielding box method for testing, the standard triangular cone is a standard part, equipped with standard coupling antennas, fixtures, etc., so the price and cost are high; moreover, during the test, the placement of the mobile phone is time-consuming, resulting in test efficiency Low; in addition, it only has a standard antenna, which cannot cover all tests for current multi-band mobile phones
