This example models the rectangular microstrip patch antenna that was analysed by Wu et al [1].  It consists of a simple rectangular microstrip antenna with the reference plane for the feed define on the edge of the patch itself.  The is model is presented in Figure 1.  Figure 1 also depicts how the rectangular patch was divided into subelements to facilitate the placement of a stripline feed element at the proper reference plane for the simulation.  S₁₁ was computed for this configuration over a wide frequency band.  Figure 2 presents the results for this computation which compare well with the published results [1, Figure 2].
