Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , the test device in the embodiment of the present invention includes a test fixture 1, which is used to simulate the connection between the mobile phone structure with antenna and the PCB board. The tester 2 is connected with the PCB board, is connected with the PCB board, and is used for testing the standing wave curve of the antenna that is simulated with the PCB board, and determines that the standing wave curve is at the decision frequency point Standing wave value; judging whether the difference between the standing wave value of the antenna at the decision frequency point and the standing wave value at the preset decision frequency point is within the limit value range, and when it is judged to be yes, determine the The performance...

Abstract

The embodiment of the invention discloses a method for testing the antenna performance of the mobile phone and a testing device, wherein the method includes: performing the analog connection of the mobile phone structure with the antenna with the PCB board; testing the standing wave value of the antenna at the adjusting frequency point on the structure piece through the testing device, and adjusting whether the difference of the preestablished adjusting frequency point is in the limited range, if true, determining the performance of the antenna is eligible, otherwise the determining the performance of the antenna is not eligible. Through the invention to test the performance of the antenna, the factors including the material of the antenna and the change of the antenna forms on the performance of the antenna are controlled, and the operation is simple, which effectively advances the producing efficiency.

Description

technical field [0001] The invention relates to a test method, in particular to a method and a test device for testing the performance of a mobile phone antenna. Background technique [0002] As an important part of the mobile phone, the antenna has a huge impact on the radio frequency performance of the mobile phone. Only when the performance of the antenna is guaranteed, the radio frequency performance of the mobile phone can be guaranteed. [0003] Most of the current mobile phone antennas are built inside the mobile phone and become part of the mobile phone structure. This not only saves space, but also saves corresponding costs. In order to further reduce the cost, the metal sheet of the antenna is usually fixed on the casing of the mobile phone by hot melting or other methods, so as to achieve the purpose of reducing the cost and saving the space of the mobile phone to the greatest extent. [0004] The wireless performance of the built-in antenna is related to many ...
