Example Overview
Calculate the input impedance of a microstrip patch antenna close to 2.8 GHz. The substrate is considered as an infinite planar multilayer substrate as it is more resource efficient. The substrate is then modelled as a finite substrate to make it a more realistic model.
A finite substrate is discretised into triangles and will therefore add to the total number of triangles.
