Description

A quick lock structure, antenna unit and Install the base

technical field

The invention relates to arrayed antenna technology, in particular to a structure and installation structure capable of quickly installing and dismounting antenna units.

Background technique

In the arrayed antenna system in the high frequency band, it is often faced with the situation that multiple antenna elements are arranged densely and in a matrix. The structural design of this type of system is often constrained by several aspects: on the one hand, in order to improve the gain performance of a single antenna unit, each antenna unit needs a sufficiently large effective aperture, that is, the size of the antenna unit is large; on the other hand, Due to the limitation of the half-wavelength of the beamforming or the limitation of the system design index, the distance between adjacent antenna elements is small, so that the arrangement of the antenna elements is quite dense. Under ideal design conditions, the gap between adjacent antenna elements is even less than one millimeter.

At present, the usual installation structure of the arrayed antenna system is shown in Figure 1a and Figure 1b. Flanges and screw holes are set at the root or waist of the antenna unit, and the antenna unit is installed one by one in the form of screw and thread connection. The advantage of this installation method is that the polarization direction (or installation angle) of each antenna unit can be positioned by screws. The disadvantage is that the disassembly and maintenance space between the densely arranged antenna units is extremely small, the installation and maintenance tools are not easy to reach, and the maintenance is inconvenient. For example, when an antenna unit in the middle area of the arrayed antenna system needs to be disassembled and replaced, it is often necessary to disassemble the antenna units one by one from the edge until the maintenance tool can reach the fastening screw of the antenna unit to be replaced, and the installation can be resumed. Then carry out the above operations in reverse, making the efficiency of disassembly and maintenance low. There is a realistic demand for a quick-lock structure designed for quick disassembly and installation of antenna units.
