Rectangular Microstrip Antennas – A Tutorial

Abstract

In this paper a full review and tutorial of Rectangular Microstrip Antennas (RMA) are carried out. The most important models of this sort of antennas are analyzed in this article and are present in a relevance order: transmission line, cavity model and full-wave. With the aim of supporting educational purposes and training in antenna design, some useful response plots are included and compared with full-wave simulations in both cases, before and after the structure optimization. The main results of this work were contrasted using returning losses and antenna directivity, for some practical variations of the dielectric constant and thickness of the substrate. Antenna patterns and return losses were also simulated and optimized using a full-wave simulation tool
