Optimization Design of Feed Tower for High-frequency Band Multi-beam Antenna on Satellite

Aiming at the layout of a certain feed array for multi-beam antenna on satellite, a feed tower design method based on 3D printing technology is proposed. This design method uses aluminum alloy 3D printing to form the main support structure under the premise of avoiding the installation holes and layout positions, and adopts the combination of the main structure of the honeycomb lattice and the local solid structure to reduce the structural quality. The mechanical analysis and optimization of the design model are carried out by combining the actual test data of the mechanical test plate and ANSYS, in which the actual product is tested and verified. The light feed tower can fully meet the requirements of high-frequency multi-beam antenna feed array for high precision and lightweight, which has a certain reference value for the miniaturized design of the antenna.
