Edge-Fed, Planar Multilayer Substrate Model

Model a microstrip patch antenna using an edge feed and a planar multilayer substrate (Green’s functions). The patch antenna is solved with MoM.

Note: This example is for demonstration purposes only. For practical applications the patch should be inset-fed by the feed line to improve the impedance match.

To improve accuracy, the length of the edge used for the edge port should be less than 1/30 of a wavelength (around 3mm for this example). For demonstration purposes, an edge length of 4.5 mm is used.
