doi:10.3901/JME.2020.09.029

Abstract

Abstract: With the continuous development of space technology, satellite communications, deep space exploration and other fields have put forward higher requirements for satellite antenna. As a kind of satellite antenna, mesh antenna has the characteristics of large aperture, high receiving ratio and light weight, which makes it an important form of satellite antenna. However, due to the inherent structure of the mesh antenna, surface shaping of the traditional mesh antenna is not achievable. In order to achieve the mesh reflector shaping goals, a cable-net structure of three-layer network is designed, and a pre-tension design method of shaped mesh antenna for three-layer network is proposed. Using this method can solve the pretension of the shaped mesh reflector of the three-layer of net structure, using the finite element software to verify the results show that this method calculated pretension can make three-layer net structure nodes in the design position and achieve balance state, proved that the method is correct and feasible.

Key words: three-layer net structure, pretension, mesh reflector, shaped
