Automatic test method for mobile phone antenna radiation performance

Abstract

The invention belongs to the technical field of 3G mobile phones, in particular to a test method for mobile phone antenna radiation performances, which comprises firstly testing the total radiation power of a mobile phone, calculating the gain of a mobile phone antenna according to the total radiation power, setting the gain value of the mobile phone antenna as the loss value of up link and down link of a terminal all-purpose tester, setting a reference power value as a critical reference power value of the omnidirectional sensitivity measurement, wherein the set reference power value will be extremely close to the critical reference power value therefore, thereby guaranteeing the chain path in the test process connecting. The test method can be used to find the reference power value meeting the requirement only by testing twice, simultaneously, and can test the total radiation power of the mobile phone antenna, thereby increasing the test efficiency and the test stability.

Description

technical field [0001] The invention belongs to the technical field of 3G mobile phones, and relates to a method for testing the radiation performance of mobile phone antennas. Background technique [0002] The radiation performance of mobile phone antenna directly affects the communication quality, so it is of great significance to test its radiation performance quickly and accurately. The CTIA (Cellular Telecommunications & Internet Association) standard points out that the total radiated power TRP and the total isotropic sensitivity TIS are two important indicators to effectively measure the performance of mobile phone antennas. Among them, the total radiated power TRP can comprehensively measure the transmitting situation of the mobile phone, and the total omnidirectional sensitivity TIS can comprehensively measure the receiving performance of the mobile phone. The formula for calculating the total radiated power TRP is: [0003] [0004] In formula (1), θ and φ are...

AI Technical Summary

Problems solved by technology

It is relatively simple to use a comprehensive tester to test the mobile phone’s transmission power, but in the prior art, when testing the mobile phone’s receiving reference sensitivity, the mobile phone is easy to break the link. It is easy to re-establish the link for 2G mobile phones, but for 3G mobile phones when measuring the omnidirectional sensitivity In the process, once the link is disconnected, it is difficult to reconnect, and the mobile phone needs to be restarted to reconnect. Therefore, the method of testing the antenna radiation performance of the mobile phone in the prior art is inefficient when testing 3G mobile phones, which is not conducive to testing
