ABSTRACT

The purpose of this thesis is the integration of a code for the analysis of array antennas with arbitrary shaped apertures, based on a full-wave Mode Matching (MM) / Finite Element (FE) / Method of Moments (MoM) hybrid method. The component elements of the array can be of different kind and, due to the flexibility of FE, not necessarily of conventional shape.

The hybrid method mentioned above has been combined with other two methods, i.e., the Fast Matrix Generation (FMG) and the Characteristic Basis MoM (CBMoM), which allow to considerably reduce the computational time as well as the memory requirements for the analysis of electrically large arrays of aperture antennas large. In fact, these two methods revealed able to reduce the computational complexity of the admittance matrix for the MoM solution.
