Abstract
In this article, we present two models to predict the quality factors for computing the impedance, bandwidth, and gain for a superstrate-loaded rectangular patch antenna. These models employ a set of CAD-oriented closed-form expressions based on conformal mapping, transmission line, cavity model, and single resonant parallel L-C-R circuit. These models are very simple and take less computational time. The accuracy of these models is verified against experimental results. This structure is also validated with the HFSS computation results.
