CAD for the synthesis of rectangular microstrip antennas

There are many powerful CAD-packages for the analysis of microstrip antennas. But the literature hasn't reported any CAD-package for the synthesis of this type of antenna. A PC software for the synthesis of coaxially fed rectangular microstrip antennas is presented, using the improved transmission line method to predict the input characteristics of a rectangular microstrip antenna. Results are shown in which there is good agreement between the synthesis and experimental results obtained by other authors.
