Array Antennas With Jointly Optimized Elements Positions and Dimensions Part I: Linear Arrays

The paper describes a deterministic algorithm based on simple analytical expressions for designing linear sparse array antennas, composed of not overlapping linear sub-apertures with pre-assigned power levels, where the positions and the dimensions of the radiating elements are jointly optimized and exploited. The obtained arrays permit maximizing the aperture filling and, as a consequence, the aperture efficiency and directivity.
