CAD of Rectangular Microstrip Antennas

Abstract

New simple computer-aided design formulas for the rectangular microstrip patch antennas have been developed. The cavity model is used but the more accurate models for open-end effect of microstrip lines and the effective permittivity are used. That allows increasing the calculation resonant frequency accuracy. Calculations of several cases have been compared with the conventional cavity calculations, expressions generated by curve fitting to full wave solutions and experimental values.
