Design and analysis of rectangular microstrip patches embedded in electromagnetically anisotropic composite laminates

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.
