低风载平面抛物面天线的反射面为网格状,网格上粘贴作为移相器的偶极子单元。该天线可极大地降低风载并减轻重量。文中采用矩量法分析了交叉偶极子单元的散射特性,并探讨了天线的性能、特点和设计方法。制作了一个2 m×2 m的C波段试验天线,测量结果与分析计算结果较为一致。

A wire-mesh flat parabolic surface(FLAPS) reflector with dipoles attached on the string offers low windload and light weight.In this paper,we present the characteristics of a C band wire-mesh FLAPS.The phased characteristics of crossed dipoles are calculated with MoM.The performances and design methods of wire-mesh FLAPS are discussed.A C-band experiment antenna is made.Test results are consistent with the theoretical analysis.
