Abstract :
In this paper, we present an efficient new modal analysis which is needed to evaluate a 1-D periodic phased array planar structure excited by arbitrary located sources. The latest requires an accurate study that permits to analyze the modal input impedance in one unit cell with the proper current density appeared on the metal part including the source domain. The formulation that is proposed to solve the problem allows to study all neighbouring elements in a periodic environment. One numerical method is used for modeling the proposed structure: the moment method MoM.
