Aperture Coupled Patch Antenna

Calculate the input reflection coefficient of an aperture coupled patch antenna. Use continuous frequency sampling to minimise runtime. Compare results for a finite and infinite dielectric.

Model the dielectric layers with two methods:
  1. Model the patch antenna using a finite substrate where the aperture is modelled as an explicit (unmeshed) hole. The patch antenna is solved with the MoM (SEP).
  2. Model the patch antenna using an infinite multilayer substrate where aperture triangles allow the energy to couple through an infinite PEC ground plane.
