Estudo paramétrico de antena patch retangular com anel fendido

This article presents a rectangular patch antenna initially designed for the frequency of 5.8 GHz with truncated ground plane and a rectangular slot in the patch in order to verify the influences of these changes in antenna radiation behavior. The purpose is to parametrically analyze the effect of the change in ring widths as well as compare with a standard rectangular patch antenna. It was demonstrated that the frequency of operation, antennas bandwidth was altered and, in some cases, the antenna presented new resonant modes.
