Abstract
In the present work, the modeling of microwaves planar circuits is proposed with an original method based on the Waves Concept Iterative Process (WCIP). It consists in the development of simulation software based on an iterative method. The iterative method is developed from the fast modal transform on a two-dimensional fast Fourier transform (FFT) algorithm. The method has been applied to the characterization and the modeling of patch antennas with notches in microstrip and coplanar technology and the quarter wavelength directive coupler. The obtained results are very powerful and successfully compared to others methods in term of time and reliability of convergence and particularly the accuracy of the results obtained in comparison with previous works.

Summary
The planar circuits are characterized by there abilities to integrate important electronic elements. The integral formulation of the transmission line modeling (TLM) method [2] is usually defined in the time domain but is expressed in the spectral domain in [3]. This spectral representation is the basis of a proposed procedure called the wave concept iterative procedure (WCIP). The result is approached progressively by successive iterations until its convergence This technique avoids the undesired phenomenon of unbounded operators; relations between currents and fields, obtained using unbounded impedance operators, are transposed to relations between waves, supplied by bounded scattering operators [5]. Good agreement between the simulation and measurement has been obtained
