摘要
采用阻抗匹配技术,利用金属栅网电调谐单元,对大型分块介质天线罩的板块接缝(或称加强肋)进行了电调谐优化设计,优化设计的含有金属栅网的混合介质结构,在保证接缝结构力学性能的前提下,其透波性率比板块接缝本身的透波率提升约20%,而且通过加载不同的金属栅网,可以调整混合结构最佳透波的频率范围,从而可用于不同频段天线罩的研制,为研制高性能大型介质天线罩提供了一条新的技术途径。
By applying the impedance matching technique and using metallic wire grid electrical tunable unit,the optimization design of electrical tunable was performed for plate joints （or reinforcing rib）in large partitioning die-lectric radome.On the premise of guaranteeing mechanical performance of joint structure,the transmission efficien-cy of optimized mixed dielectric structure containing metallic wire grids improves by about 20% compared with plate joints.In addition,by loading different metallic wire grids,the frequency range of best transmission for mixed structure can be adj usted,thus can be used to develop radomes of various frequency.This provides a novel techno-logical pathway to design high-performance large dielectric radomes.
