Mode Scattering Analysis of Large Scale Antenna Array

The electromagnetic mode scattering of large scale antenna array is approximated in this paper. The radiation pattern of the large array is simulated with HFSS software using array synthesizing function firstly, and then, the radar cross-section (RCS) is obtained by some simple formulations. It is efficient to analyze the mode scattering of large scale antenna array including some large scale phased array with this method.
