This paper presents a method for the efficient analysis of multilayered frequency selective surfaces (FSS) integrated with phased arrays of open-ended waveguides. Using the unit periodic cell approach, the structure is represented as an equivalent multi-mode transmission line network, where each periodic surface (array or FSS) is characterized by an equivalent immittance matrix, computed through a full-wave
analysis based on the method of moment technique. This approach provides an useful tool for the design of integrated planar FSS for phased array antennas. The first objective in the design process, is the rejection of out-of band harmonics for inter-antenna coupling reduction in complex environments.
