| 摘 要： | 折叠波导缝隙阵天线在太空中展开时可能产生的应力形变会影响其辐射特性,因此在设计时需要充分研究形变的机理和可能产生的影响.本文首先分析和计算薄膜波导在展开时受到拉伸而可能产生的形变,然后分析了形变带来的波导特性阻抗等的变化,以及由此导致的波导缝隙阵天线的驻波、增益以及副瓣电平等辐射特性的变化.该分析方法联系了波导所受外力和电磁场特性之间的关系,为实际工程提供有益的理论指导. |

| Abstract: | The radiation characteristic of the folded waveguide slots array antenna could be affected by the expanded deformation in space;therefore the mechanism and effects of deformation are important to take into account.The deformation of the membrane waveguide expanded by the force is analyzed with finite element method at first.Then,the effects on character impedance due to the waveguide deformation is presented and the radiation characteristics of membrane waveguide slots array antenna such as VSWR,gain and si... |
| Keywords: | folded membrane waveguide expanded deformation waveguide slots array antenna |
