“…Full wave analyses of antenna performance in time domain, 6 in spectral domain, 7 and by approximation method 8 were applied to show that the resonant frequency is decreased by the overlay (when embedded) due to surface wave loss. 9 Similar investigations on microstrip antenna with dielectric overlay 10 and oxide overlay 11 also confirmed that the embedding can reduce antenna gain substantially. The above studies, however, were limited to antenna on isotropic structures.…”

Composite structures with desire mechanical properties can be tailored to embed microstrip antenna in aerospace systems for reducing aerodynamic disturbance. The performance of a rectangular microstrip antenna in composite structures is analyzed in spectral domain in this work. Analysis shows that the electromagnetics of antenna in spectral domain is similar to the mechanics of composite structure in space domain. The electrical field, the immittance (impedance or admittance), and the current density are equivalent to the stress, strain, and stiffness in mechanics of composite structures. The governing equations, though may be of different dimensions, are also similar. It shall be expected that the performance of a microstrip antenna on composite structures is different from that on isotropic structures; just as the mechanics of the former is so different from that of the latter. Analysis confirms that antenna performance depends on the structure's electromagnetic properties; similar to the mechanics of composite structures depends on the laminate layers' ply angle and stacking sequence.
