Abstract：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.
