    摘要: Fiber-reinforced composite structures can be tailored to desire mechanical properties and to embed microstrip
    antenna in aerospace applications. The electromagnetic characteristics of a microstrip antenna on isotropic and
    uniaxial substrates have been known, but that embedded in composite laminated substrates remain unavailable
    to date. This work aims at analyzing the performance of microstrip antenna embedded in composite laminated
    substrates by spectral domain analysis. Parameter studies are conducted to investigate the effects of the substrate’s
    dielectric constants, the fiber directions (the orientation between the antenna and the laminate layers), and the
    stacking sequence on antenna’s resonant frequency and radiation pattern. The antenna size when embedded in
    composite laminated substrates is larger than that when attached on isotropic substrates, or conversely, the
    resonant frequency will deviate lower if assuming the substrate as isotropic. The far-field pattern in composite
    laminated substrates is more ‘directional’ than that in isotropic substrates. The antenna gain in the substrates of
    symmetric stacking with ±45° fiber direction is 20 dB better than that in isotropic substrates in some elevations.
