Test system of wireless terminal

Abstract

The invention discloses a test system of a wireless terminal. The system comprises a measured piece, a shielding box body, a test antenna and an absorption screen, wherein the measured piece is a wireless terminal; an internal wall of the shielding box body includes a reflecting portion and an absorption portion, and a reflecting portion surface is at least metal, the reflecting portion is used for carrying out total reflection on a wireless signal transmitted by the wireless terminal, and the absorption portion is equipped with an wave absorbing material and is used for absorbing a radio wave; the test antenna is used for carrying out wireless communication with the measured piece; a material of the absorption screen is a wave absorbing material, and the absorption screen is arranged between the measured piece and the test antenna and is used for absorbing the radio wave; a position relation of the measured piece, the test antenna and the reflecting portion corresponds to a same ellipsoid body; the measured piece and the test antenna are arranged at two focal point of the ellipsoid body respectively; and the reflecting portion is arranged on an ellipsoidal surface of the ellipsoid body. The test system of the wireless terminal in embodiments of the invention has advantages that a test result repeatability error is small, a test result is stable, test efficiency is high, cost is low and so on.

Description

technical field [0001] The invention relates to the technical field of wireless terminals, in particular to a testing system for wireless terminals. Background technique [0002] With the development of wireless terminal (such as mobile phone, tablet computer, etc.) technologies, wireless terminals have entered many aspects of daily life. The demand for mass production of wireless terminals leads to the demand for rapid testing of wireless terminals. Therefore, a radio frequency testing system capable of rapidly testing wireless terminals needs to be proposed, so as to produce terminal products with quality and quantity. [0003] Since the antenna of a mobile wireless communication terminal is usually not a directional antenna, but radiates in all directions in space, according to the test standard of CTIA (US Wireless Communications and Internet Association), the wireless performance test of the wireless terminal is defined as OTA (Over-The-Air, space port communication p...

Problems solved by technology

[0006] However, the measurement speed of the current test system is relatively slow, and because the distance between the test antenna and the DUT is required to be greater than the far-field distance, so that the DUT is exposed to the plane wave irradiation of the test antenna, this results in a large measurement system. Manufacturing High cost and small scope of application are not conducive to large-scale quality inspection of wireless terminals
