## CALCULATION OF THE MUTUAL COUPLING PARAMETERS AND THEIR EFFECTS IN 1-D PLANAR ALMOST PERIODIC STRUCTURESBy B. Hamdi, T. Aguili, N. Raveu, and H. Baudrand
Abstract:
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 their effects integrating a large planar radiating structure. Two different formulations are suggested, in spectral and spatial domains, to solve the problem and to calculate the coupling coefficients between the neighbouring elements in a periodic environment. Important gain in the running time and used memory is obtained using Floquet analysis. One numerical method is used for modeling the proposed structures: the moment method combined with Generalized Equivalent Circuit (MoM-GEC).
