Abstract

In this paper the problem of a rectangular microstrip antenna printed on a uniaxial substrate with a superstrate loaded is treated. The effects of superstrate on the complex resonant frequency of the rectangular microstrip antenna on a uniaxial substrate is studied. Special constitutive relations are used in describing the uniaxial properties of the matrial, such as the dyadic Green´s function can be formulated. Electromagnetic fields and boundary conditions in the spectral region were used in finding Green´s function. Using Galerkin´s method in solving the integral equation, the complex resonant frequency of the antenna is studied with sinusoidal basis functions, which show fast numerical convergence
