    摘要: In high performance aerospace systems where weight and aerodynamics are of major concern, fiber
    reinforced composite laminates can be tailored to achieve desirable mechanical properties
    and accommodate low-profile microstrip antenna. This work aims at the analysis of microstrip
    antenna array embedded in composite laminated substrates. The size of a single antenna is first
    calculated by spectral domain analysis to model the effects of the substrate’s electromagnetic
    property and the orientation of the laminate layers. The antenna array as well as the feed network,
    composed of microstrip transmission lines, quarter wave-length impedance transformers, and
    T-junction power dividers, is then tuned to accommodate the effects of the coupling between the
    antenna elements and the feed network loss. The performance of the 1 × 2, 1 × 4, and 1 × 8 linear
    array and 2 × 2 and 2 × 4 planar array are shown to have better directivity when embedded in
    composite laminated substrate compared with those when attached on isotropic substrate. Both 1
    × 2 and 1 × 4 arrays at 2.4 GHz are validated experimentally to achieve better coverage.
