Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 It is a schematic diagram of the test system of the omnidirectional radiation power of the mobile phone provided by the present invention. Such as figure 1 As shown, the test system includes a full anechoic chamber, a rotating table, a measurement antenna and a communication antenna. The rotating table is placed in the full anechoic chamber, and the mobile phone to be tested is clamped horizontally on the rotating table. The rotating table can drive the mobile phone horizontally. The range of the rotation angle phi is 0°≤phi≤360°, the range of the vertical rotation angle theta is 15°≤theta≤165°, and the measurement antenna and the communication antenna are fixed on the wall of the dark room.

[0021] Fig. 2 is a flow chart of the method for testing the omnidirectional radiated power of the mobile phone provided by the present invention. As shown in...

Abstract

The invention relates to a method for quickly testing the omnidirectional radiation power of a mobile phone, and belongs to the technical field of radio frequency testing of wireless communication products. The test method can quickly obtain results only based on tests at limited positions combined with a linear interpolation method, thereby greatly reducing the number of test positions, shortening test time, and improving test efficiency.

Description

technical field [0001] The invention relates to a method for quickly testing the omnidirectional radiation power of a mobile phone, and belongs to the technical field of radio frequency testing of wireless communication products. Background technique [0002] As a portable wireless mobile terminal product, the actual use effect of the mobile phone will be severely restricted by its radio frequency performance. Therefore, many aspects of mobile phone research and development, production, certification, etc. will involve the testing of radio frequency indicators such as its omnidirectional radiation power. In many domestic and foreign standards, the testing system and method process of the omnidirectional radiation power of mobile phone mobile stations have been made. For example, "CTIA Test Plan for Mobile Stations RF Power and Receiver Performance" formulated by Cellular Telecommunication & Internet Association (CTIA), and the communication industry standard YD / T1484 " Mobi...
