This chapter introduces an overview of coplanar technology and the general techniques and process to improve the response and characteristics of microwave components. A new circular defected ground structure (DGS) with shaped coplanar line is investigated for compact stopband filter (SBF) for microwave and millimeter wave applications. With this structure, the response of resonant element in 20 GHz exhibits the bandstop function. The proposed DGS is also modified by introducing four symmetrical slots with L-configuration in conductor line of a coplanar circuit to improve separately the stopband and passband performances. An equivalent circuit model derived for the proposed structures will be provided.

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.
