Unconventional techniques for the synthesis of modern antenna arrays

International audienceIn this work, the synthesis of clustered antenna array architectures is addressed. The sub-arraying problem is formulated as a tiling one, and solved considering tiles of rectangular shape (domino). An optimization strategy is proposed to deals with medium/large array apertures, obtaining tiling configurations that are optimal in terms of aperture efficiency and sidelobe level (SLL). A simple example shows the effectiveness of the proposed approach for both square and arbitrary shaped array layouts
