The Influence of Antenna Installation Accuracy on Quality of Signal Reception

The process of shells formation, finding the position of grid elements after deformation is investigated. Minimization of potential energy is carried out numerically by iterative method. The result is the formation of antenna array by electric arc spraying method.This techonology of manufacturing shells from mesh material can be used for the manufacture of axisymmetric and non-axisymmetric reflectors or individual elements of mirror antennas.

In the course of the work, the process of forming reflective shells and finding the position of grid elements after deformation was investigated. Fixation of mesh nodes by electric arc spraying. After that, a composite material such as polystyrene is applied to form reflective shells. Minimization of potential energy is carried out numerically by an iterative method. The result of the work is the formation of the antenna array shell by the method of electric arc spraying and the application of the composite material. The following forming operations of sheet metal stamping are known: drawing, rotary drawing, relief forming, trimming, including rubber and liquid drawing, hydromechanical drawing, explosion drawing, electric discharge stamping, electromagnetic stamping, hydropneumatic drawing, which allow to obtain a shell from sheet material (solid or gas and water permeable) by pressing it against a die or punch with a transfer medium.
