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 using the impedance matching technology, the metal mesh network tuning unit is used to electrically tune the plate joints (or stiffeners) of the large segment dielectric radome, and the optimal mixed metal mesh dielectric structure is designed Under the premise of ensuring the mechanical properties of the joint structure, the permeability of the joint increases by about 20% compared with that of the seams, and by loading different metal grids, the optimal frequency range of the transparent structure can be adjusted, Which can be used in different frequency band radome development for the development of high-performance large media radome provides a new way of technology.
