Abstract


This paper discusses one approach for modeling and designing Vivaldi antennas by an iterative method using surface impedance for reducing surface waves in antenna. The technique of the Wave Concept Iterative Procedure is based on two equations; one is in the spatial domain and the other in the spectral domain. The passage between the two domains is based on Transform Fourier Mode FMT. A comparative study is presented between the iterative method and the CST software. The results were obtained in a very reduced time compared that those obtained by the simulation software.
