Progress of Broadband Wave-Transparent Materials for Radome

综述了天线罩用宽频透波材料的发展现状,分析了影响透波材料性能的因素,系统讨论了宽频透波天线罩的制备方法。研究指出介电性能是评价材料透波性能的一个重要标准,选用低介电材料和提高材料孔隙率可实现材料宽频透波,新的介质材料的开发和研究将是今后天线罩制造技术发展的一个主要发展方向。

Research progress of broadband wave-transparent ceramic radome materials is reviewed. The influen- cing factors of wave-transparent materials performance are analyzed, and the preparation methods of ceramic radome materials are systematically discussed. It is suggests that the dielectric properties is an important criterion for evaluating wave-transparent performance. Broadband wave-transparent performance of ceramic radome can be achieved by selec- ting a low dielectric material and increasing porosity, and the development and research of novel dielectric materials is- an important dire.ction of next-generation radome material preparation.
