设计并制备了一种共形承载一体化的埋微带天线蜂窝夹层结构。利用有限元方法分析了该结构的力学性能,与三点弯曲实验比较,获得较好的一致性。研究了蜂窝层厚度等参数对电性能和力学性能的影响。结果表明,蜂窝层厚度为8~14 mm时,共形承载天线不仅具有高增益和低损耗,还具有较好的力学性能。
A honeycomb sandwich structure embedded with the microstrip antenna of conformal load-bearing antenna structure(CLAS) was designed and fabricated.The mechanical property was analyzed by finite element method(FEM).Compared with the 3-point bending test,the calculated results from FEM are agree well with those from experiments.The influences of honeycomb thickness on the mechanical and electric properties were investigated.The results show that the CLAS with 8~14 mm thick honeycomb has not only have high gain and low return loss,but also have good mechanical properties.
