摘　　要：扩大槽线单元开口渐张的比例因子并优化其他参数,压缩天线尺寸,采用金属框架结构,结合镂空和局部切割方法,实现米波超宽带天线单元小型化和轻量化设计。双极化单元正交排布,通过单元分步折叠和阵列骨架分块折叠,实现大型阵列天线自动化撤收与架设。实验阵列口径超过18 m×6 m,可在15 min内实现快速折叠或展开。实验天线的测试结果与设计一致,表明分析与设计方法正确有效,可推广应用于各种宽带天线及大型阵列天线设计。Enlarge exponential opening rate and optimize other parameters to reduce size of metallis TSA antenna for meter-wave arrays. Combine hollow out structure and topical cutting to decrease weight of the UWB （ Ultra-WideBand ） antenna. Orthogonal dualpolarized elements and parts of the array skeleton can be folded in proper order. The size of example array are more than 18 m × 6 m, and can he folded or seted up in 15 minutes. The result of test is consistent with that of the simulation design, which has indicated that the analysis and design method is effective. The result can he used in design of other UWB antennas or arrays.
