| Abstract: |
| It seems difficult for the conventional structural analysis and calculation method to ensure excellent shape to the suspension structural multi-mode multi-feed antenna,which considers the suspended cables as straight lines.Now,a new method in practical engineering is proposed for suspension structural analysis and calculation.Firstly,according with the character that the heights of suspension points are steady,the radii of suspension points can be obtained by the suspended-cable equations,and their radii are corrected by the moment equations,then the lengths of antenna wire segments are determined.This method applies to the wire antenna's rope slings influenced by focus forces with different power and space,and it ensures fine shape to the antenna.Compared with the calculating result of conventional geometric method,the result here is more accurate in practical engineering. |
