This study investigates the anisotropy substrate and dielectric cover effects of the rectangular microstrip patch antenna on anisotropy substrates with air gap, based on rigorous full-wave analysis and Galerkin's moment method. Results show that the resonant frequencies in the variation of air gap, patch length, and permittivity of superstrate can be determined and analyzed with varying dielectric cover thickness.
