ABSTRACT
In this paper, we consider the problem of numerical modeling of characteristics of a dielectric disk antenna excited by a vertical electric dipole. The problem is solved by using the method of regularization combined with the Galerkin method that enables us to obtain an infinite block-type set of the Fredholm linear algebraic equations of the second kind. The following characteristics of the antenna in the far field zone are obtained for various material and electric parameters: radiation pattern, space and surface wave powers, the absorbed power, efficiency, gain and directivity.
