Generalized Scattering Matrix (GSM) Approach for Multilayer Finite Array AnalysisAbstract
The paper presents the Generalized Scattering Matrix (GSM) approach for analyzing multilayer printed array structures. The analysis involves computation of the overall GSM of an infinite array structure, Floquet modal based analysis of mutual coupling between array elements followed by estimation of finite array characteristics. A slot-fed patch array of 225 elements is used as an example for numerical results. It is found that the input match of the edge elements significantly differs from that of the elements in the center region of the array. The advantages and disadvantages of the approach are discussed at the end.
