摘　　要：叙述了几种不同成分的配比对材料强度以及介电常数的影响,并进行了相应的分析。分析结果表明,利用磷酸或聚合磷酸铝结合空心球可研制出ε<2的介电材料,材料的研制对宽频天线罩电性能的设计有一定的参考价值。This article describes several different components ratio on the strength of the material, as well as the impact of permittivity and conducted an analysis of the corresponding ring. The results show that the use of phosphoric acid or alunfinum phosphate polymer combination of hollow spheres can be developed ε 〈 2 of dielectric material, material for broadband radome design of the electrical properties of some reference value.

关 键 词：介电常数 弯曲强度 显气孔率
