A Mode Matching - Finite Element - Spectral Decomposition Approach for the Analysis of Large Finite Arrays of Horn Antennas摘要
In this paper a Mode Matching / Finite Element / Spectral Decomposition (MM/FE/SD) approach is applied to the analysis of finite but large arrays of horn antennas. The proposed methodology retains advantages from the three involved techniques: the SD reduces the finite problem to a superposition of infinite periodic ones, whereas the flexibility of the FE method allows us to model complex irregular structures providing a very high degree of generality. A key step in the analysis consists of resorting to a stepped waveguide model of the longitudinal inner profile of the elementary horn antenna. The numerical efficiency of the MM procedure ensures the continuity of transverse fields over each waveguide discontinuity and over the radiating aperture. The methodology presented here is applied to array with elements arranged in polygonal shape.
