The synthesis of subarrayed phased antenna arrays for limited-field-of-view (LFOV) and wideband applications is addressed in this work. The tiling of the antenna aperture is obtained using polyomino subarrays of irregular shape. The position and orientation of each subarray are properly optimized by means of a strategy based on a genetic algorithm in order fill the aperture and obtain the desired radiation pattern. Preliminary results are reported to show the effectiveness of the proposed method in synthesizing subarray configurations whose resulting patterns are characterized by low sidelobes and high main-beam directivity.

Abstract
The synthesis of subarrayed phased antenna arrays for limited-field-of-view (LFOV) and wideband applications is addressed in this work. The tiling of the antenna aperture is obtained using polyomino subarrays of irregular shape. The position and orientation of each subarray are properly optimized by means of a strategy based on a genetic algorithm in order fill the aperture and obtain the desired radiation pattern. Preliminary results are reported to show the effectiveness of the proposed method in synthesizing subarray configurations whose resulting patterns are characterized by low sidelobes and high main-beam directivity.File | Dimensione | Formato | |
