Document Type and Number:
WIPO Patent Application WO/2020/125384
Kind Code:
A1
Abstract:
The present invention relates to high-precision reflective surface antenna back frame structure design technology in the fields such as communications, measurement and control, and radio astronomy, and disclosed therein is a high-precision hexagonal space double-layer reflective surface antenna back frame. The present invention aims to provide an antenna back frame that is highly precise, light weight, easy to install and suitable for mass production. The antenna back frame comprises an upper chord surface, a lower chord surface, space diagonal rods, side diagonal rods, a door-shaped frame, a connecting support, a support frame, a positioning pillar, bolt balls and so on. The outer shape of the back frame is hexagonal, comprising an upper layer and a lower layer. The upper chord surface is composed of triangular units, the lower chord surface is composed of triangular and quadrilateral units, and the upper and lower layers are combined one with the other by means of triangular cones to form a stable spatial structure. The rods of the back frame are connected to each other by means of the bolt balls. The present invention has the characteristics of good structural rigidity, is light weight and highly precise, and is particularly suitable for antenna back frame structures in large and medium-sized reflective surface antennas.
