Abstract

An antenna near-field test method and device are provided, the antenna near-field test device comprises 264 spherical probes which are spherically distributed at positions with included angle of 15 degrees with the theta axis and the phi axis of the spherical coordinate, the test method comprises that: when a signal of a transmitter of a measurement antenna product is acquired, controlling 264 probes to start simultaneously to acquire first data detected by each probe; and when the signal of the transmitter of the measurement antenna product is acquired, controlling 264 probes to start simultaneously to acquire first data detected by each probe. Calculating radiated power of the transmitter according to the first data; when a signal of a receiver for measuring an antenna product is acquired, controlling a probe of 60 target positions distributed at positions spaced apart by 30 degrees on a theta axis and a phi axis of the spherical coordinates to simultaneously start to acquire seconddata detected by the probe of each of the target positions; calculating a sensitivity of the receiver from the second data. The embodiment of the invention eliminates the influence of the artificial placement position, the different binding method, the speed of the turntable and the like on the test result, so that the test speed is fast and the test result is accurate.

Description

technical field [0001] The invention relates to the technical field of antenna testing, in particular to an antenna near-field testing method and device. Background technique [0002] With the rapid development of mobile communication, the research and development of antennas has been promoted. Antennas are used in various electronic products (such as mobile phones, tablet computers, wearable devices, etc.), mobile communication base stations, military equipment and other equipment. The speed and accuracy of antenna measurement have become the bottleneck of the enterprise's R&D process. [0003] At present, there are two popular antenna tests in the world, namely far-field test and near-field test. Among them, the far-field test, such as the macro-circle method, has relatively accurate test data, but it takes a long time and the efficiency is not very high. The near-field test speed is much faster than that of the far-field, and it is currently the main test system for ante...
