Finite element microstrip antenna simulator (FEMAS)

In this study, a FEM-based microstrip antenna simulator, namely FEMAS, has been developed. The FEMAS allows analysis and design of three-dimensional microstrip antenna elements and outcomes the related antenna parameters such as input impedance, gain, and radiation pattern. In the paper, the FEM formulation is overviewed and the features of FEMAS are presented. Also, The return loss characteristics of a microstrip antenna achieved by means of FEMAS and Ansoft HFSS are presented.
