Analysis of a thick finite microstrip antenna using surface equivalence principle and multiple network theory (SEMN)

The SEMN method was previously introduced and general formulas and derivations for the analysis of complex structures and closed-form expressions for electromagnetic fields in the source region were presented in (1997). A thick microstrip antenna with finite size substrate is analyzed by the SEMN method and its return loss and radiation patterns are calculated. It is shown that the method is a powerful tool for analyzing such structures and theoretical results are in very good agreement with measurements.
