Problems solved by technology

[0003] For antennas used in high-order multiple-input multiple-output technical scenarios, this conventional antenna structure design is more complicated and requires more assembly man-hours. Due to the large number of assembled components, it is easy to cause errors. Therefore, consistency will also be affected
[0004] The existing design scheme provides a feed system containing air microstrip lines, which uses reflectors as formations, which simplifies the design to a certain extent, but the air microstrip lines in this design scheme have obvious defects, namely : Large backward radiation, unstable voltage standing wave ratio, etc., and it is more than 2GHz frequency band because it has higher requirements for processing and assembly, so it is difficult to be adopted

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an antenna system. Background technique [0002] At present, the interior of the radome in the conventional base station antenna design system mainly includes three parts, one is the radiation array unit, the other is the reflector that constrains the orientation, and the third is installed on the reflector to provide the amplitude and phase of the radiation array unit feed system. The reflector is usually used as a carrier platform, and the radiation array unit and the feed network are connected and installed together with the reflector. [0003] For antennas used in high-order multiple-input multiple-output technical scenarios, this conventional antenna structure design is more complicated and requires more assembly man-hours. Due to the large number of assembled components, it is easy to cause errors. Therefore, consistency will also be affected. [0004] ...
