Edge-Fed Rectangular Microstrip Patch Antenna

An example of how a rectangular microstrip patch may be fed at an edge.

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 defined on the edge of the patch itself.  The is model is presented in Figure 1.  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].
