基于折叠结构实现LPDA小型化的优化设计

Optimized Design of LPDA Miniaturization Based on Folding Structure

利用波状结构可以初步实现LPDA的小型化。因此,在此基础上引入折叠结构进行优化设计。具体地,对传统结构、波状结构和折叠结构的性能展开对比,结合三维增益方向图,初步验证了折叠结构优化的可行性。最后设计实验方案,进一步验证了折叠结构的优势。

The miniaturization of LPDA can be realized by using the wavy structure.Therefore,the folding structure is introduced to optimize the design.Specifically,the performance of traditional structure,wave structure and folding structure are compared,and the feasibility of folding structure optimization is preliminarily verified by combining with three-dimensional gain pattern.Finally,the experimental scheme is designed to further verify the advantages of folding structure.
