An eigen space approach for the synthesis of linear and circular arrays

An eigenspace non-iterative technique for the synthesis of both linear and circular arrays is introduced in this paper. The technique is applicable in case of equispaced linear arrays with equal phase and symmetric excitation coefficients and circular arrays with quadrant symmetry with number of elements divisible by 4. The technique is based on formulating the synthesis process as a least-squared optimisation problem. Some design examples are presented to illustrate the potential and the quality of the considered technique
