Raphael, I don't know.....I'm not smart enough to find "holes" in the numerical electromagnetics code.? I do know that there is no equation for any particular antenna configuration in the modeling/simulation process.....it just treats each small part of the antenna in question according to Maxwell's equations and combines the results.? I view it as a good agnostic test.

Regarding the general question of creating a lumped antenna model....here is a link to a presentation which gives a good idea of what is involved...even for creating a lumped model of a dipole antenna's impedance vs. frequency.
There are many other useful presentations that the author (Steve Stearns, K6OIK) has created on that same page,? He's a genuine authority on antennas and modeling.
