Abstract

The invention relates to the technical field of wireless communication, and provides an antenna test system, method and device, electronic equipment and a storage medium, and the system comprises a radio frequency device for outputting a radio frequency signal and a to-be-tested multi-port antenna, and especially comprises a control device, a switching device and at least two power dividers. Eachpower divider is connected with the switching device and the radio frequency device; the control device is connected with the switching device and used for determining a target power divider meeting test requirements according to current test requirements and controlling the switching device to enable the target power divider to be connected with the to-be-tested multi-port antenna. A plurality ofpower dividers corresponding to the test requirements are adopted, the on-off condition of the switching device is controlled according to the test requirements, and the target power divider meetingthe requirements can be connected with the to-be-tested multi-port antenna, so that different working states of the to-be-tested multi-port antenna can be automatically tested, the overall test efficiency is improved, a connection error caused by disassembly and assembly can be avoided, and the test accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an antenna test system, method, device, electronic equipment and storage medium. Background technique [0002] With the development of wireless communication technology, limited radio frequency resources are facing increasing communication demands. More and more wireless communication systems introduce multi-port antennas to improve system capacity, coverage and system throughput. Taking China Mobile's commercial 4G mobile system TD-LTE as an example, the base station mostly adopts 8-antenna configuration. Among them, in order to further improve the system channel capacity, the base station may need to increase to 32 antennas, 64 antennas, or even 128 antennas. [0003] In order to simulate and verify the performance of antenna multi-beamforming, the existing technology generally uses figure 1 The antenna test system shown in , adopts the following method...
