Solving electromagnetic scattering and radiation problems with moment methods or finite element methods over a large frequency band gives accurate results, but it is often too time-consuming. So we propose a fast auto-adaptive method to optimize the computational electromagnetics solver applied in the case of various radiating and dielectric structures. This method is able to generate the electromagnetic behavior of the antenna with a very few simulations over a broad frequency band.
