本文提出了保型杆式的天线保型结构,基本思想为用保型杆实现对反射体的轴对称支撑。调整保型杆的刚度使反射体的支撑点在抛物面轴向等柔。此型式特别适宜于克服波束波导体制给保型设计带来的困难。在对结构布置进行多次试算与调整后,用虚功准则法进行优化,并对虚功法在天线结构设计中的应用作了改进。结果达到了较高的精度。
In this paper, Paul-type antenna-type antenna protection type structure, the basic idea for the use of Paul-type reflector to achieve axisymmetric support. Adjust the rigidity of the stylus so that the supporting point of the reflector is equal to the axial direction of the parabola. This type is especially suitable for overcoming the difficulties that the beam waveguide system imposes on the warranty design. After several trial and adjustment of the structure layout, the virtual work principle is used to optimize, and the application of virtual work method in antenna structure design is improved. The result reached a higher accuracy.
