Symmetry considerations in analysis of finite microstrip antennas using SEMN method

Abstract

Using surface equivalence principle and multiple network theory (SEMN) a rigorous method has been introduced for the analysis of finite microstrip antennas [l]. One practical limitation of rigorous methods is that they need extensive CPU time and storage to analyze a finite structure which is not too small electrically. In this article, three symmetry considerations are introduced to reduce the number of unknowns and computations and eliminate this drawback.
