A Biorthogonal-Mode Based Approach to Pattern Synthesis for Array Antennas
一种基于双正交模的新型天线阵方向图综合方法

A novel approach to arbitrary array pattern synthesis based on biorthogonal modes is presented in this paper. The algorithm involving arrays with arbitrary geometry and incorporating mutual coupling effect, can accurately determine element excitations required to yield desired patterns. The mutual orthogonality of modes is used to ensure the agreement between the desired and computed patterns. When the weighted field is applied, the double integral can be simplified by performing one variable integral, so synthesis procedure is less time-consuming. The effectiveness of the approach is demonstrated with several numerical examples.
