In this paper the method of analytical regularization combined with the Galerkin method has been proposed to determine the fundamental antenna effects of a circular lossy patch antenna on dielectric substrate backed by a perfectly conducting ground plane and excited by a vertical electrical dipole. Due to analytical regularization the dual integral equation in transform domain proved possible to convert into the infinite matrix equation of Fredholm second kind. This matrix equation has been solved by means of the efficient numerical procedure. Antenna characteristics, such as surface and space wave power, radiation patterns and radiation efficiency have been obtained for different values of patch resistivity and results are discussed.
