Abstract

This paper proposes an innovative antenna module where the microstrip antennas are embedded in composite laminates. The electromagnetic fields of the anisotropic medium by using Hertzian potentials will be derived to form the bases to develop the electromagnetic model of anisotropic composite laminates and the dimensions of radiators at desired operating frequency are solved by the spectral domain immittance functions with Parseval's theorem and Galerkin's method. Analyses show that ply angle, anisotropy ratio and stacking sequence are critical to performance and the composite laminates embedded with microstrip antennas will be a good candidate in aerospace communication applications.

电磁各向异性复合材料层板中嵌入矩形微带贴片的设计与分析
本文提出了一种将微带天线嵌入复合层压板的新型天线模块。利用赫兹势推导出各向异性介质的电磁场,为建立各向异性复合材料层合板的电磁模型奠定了基础,并利用Parseval定理和Galerkin方法,利用谱域阻抗函数求解了期望工作频率下辐射体的尺寸。分析表明,厚度角、各向异性比和叠加顺序是影响微带天线性能的关键因素,微带天线复合材料层压板在航空通信领域具有良好的应用前景。
