How to design a broad bandpass filter in the X-frequency range? The design procedure is developed from synthesis to electromagnetic simulation. The filter to be designed is implemented in waveguide technology with inductive irises coupling sections. So as to evaluate equivalent susceptance of iris aperture, two methods were used: the first one is based on(More)
The purpose of this paper is the establishment of the adequate choice of trial functions used in the transverse resonance method for modeling asymmetric coupled microstrip structures for C- and pi-mode in full-wave domain. So, two kinds of the set of cosine trial functions are used (one takes into account the edge metallic effects and other does not take(More)
—This paper proposes a new modal analysis based on Floquet's theorem which is needful for the study of a 1-D periodic phased array antenna excited by arbitrary located sources. This analysis requires an accurate estimation for calculation of the mutual coupling parameters (for example: mutual impedances or admittances. . .) between the array elements and(More)
Due to the practical importance and difficulties associated with their closed form solutions, the experimental and computational study of periodic planar multilayered structures, such as FSS in multilayered configuration and Multilayered Planar antennas array, are in complementary progress. During the past two decades, the widespread use of such methods has(More)
This paper presents an efficient implementation of waves' concept based on the iterative method algorithm combined with the FFT-2D algorithm adapted to box modes, or Fast Modal Transform (FMT). The advantages of this method are simplicity and the no implication of basic functions and matrices inversion. As used in other calculation's methods, this work(More)
—Studying of mutual coupling parameters between the antenna elements in an array environment has been considered as the subject of feature research. That is why, in this paper, we present a new Floquet modal analysis procedure for analyzing almost periodic structures. Accurate evaluation of the mutual coupling could be achieved by this analysis. It is shown(More)
