In this work, we propose a solution to deal with the problem of the errors introduced by the presence of discontinuities in planar microstrip circuits in computing some physical quantities, like the distribution of the current, by the moment method (MoM).This approach combines the Moment Method with the generalized equivalent circuit method to analyze a planar circuit. The interest of the method is the use of the attachment functions in the base of trial functions in the moment method, generally one or two functions by interface.In order to assess its efficiency, the proposed method is developed for analyzing discontinuities in a rectangular microstrip antenna. To achieve this purpose, the current traveling on the feed line toward the patch edge is calculated and the coupling coefficient of a rectangular microstrip antenna array in if-plane configuration is investigated. The convergence study of the matrix in TE and TM mode is highlighted.
