Embodiment Construction

[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0043] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ...

Abstract

The present invention relates to an antenna near-field test device and method. The device is used for testing an antenna. The device comprises a multi-probe array, a front-end processing module, a driving mechanism, a synchronization module and a signal acquisition and processing module; the multi-probe array comprises a plurality of probes, wherein the probes are distributed linearly along a straight line; the front-end processing module is electrically connected with each probe; the driving mechanism is in driving connection with the multi-probe array; the driving mechanism is used for driving the multi-probe array to move along a direction perpendicular to the straight line; the synchronous module is electrically connected with the driving mechanism; the synchronization module is electrically connected with the signal acquisition and processing module; and the signal acquisition and processing module is electrically connected with the multi-probe array and the antenna. The multi-probe array traverses the near-field area of the antenna under the driving of the driving mechanism, the plurality of probes of the multi-probe array detect the antenna in a simultaneous or time-division manner, so that the detection of the multi-probe array can fast cover the near-field area of the antenna, and therefore, the detection efficiency of the antenna can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of antenna testing, in particular to an antenna near-field testing device and method. Background technique [0002] Phased array antennas are gradually replacing fixed beam array antennas in various fields due to their powerful beam electronic scanning function, flexible application, and field-renewable beamforming capabilities. In the fields of synthetic aperture radar, 5G communication antennas, etc., in order to meet the requirements of multi-function, multi-mode, and high adaptability, phased array antennas are required to realize massive beamforming to cope with various working conditions and application scenarios. Greatly increase the testing workload of phased array antennas. [0003] The near-field test of the phased array antenna can be carried out all-weather and all-weather, the site size requirement is small, the test efficiency is high, and the two main test functions of channel calibration and...
