Abstract :
In this paper, we study the effects of the uniaxial permittivity anisotropy of the substrate, on the resonant frequency and the bandwidth of a rectangular microstrip antenna of the structure as: substrate; patch; superstrate. The problem is rigorously formulated by using the integral equation based on the dyadic spectral Green´s function. To obtain the complex resonant frequency of mode TM01, the method of Galerkin have been used to solve the integral equation, by choosing sinusoidal basis functions. The results obtained are compared with the isotropic substrate case.
