A Study of Periodic Microstrip Structures Using Finite Elementary Lines (FEL) Approach

This "Paper" presents a comparison of the results obtained by means of the Finite Elementary Lines (EEL) approach to those obtained by other authors in the characterization of periodic microstrip structures on the localization, the width at - 20 dB and the depth of the rejection band. Designers of stop-band or pass-band filters find in this approach of FEL a safe and effective way to get inexpensive design and achievement that best meets their expectations.
