Abstract
In this report, the synthesis of simultaneous multi-beams through time-modulated linear arrays is studied. Unlike classical phased arrays where the antenna aperture is usually shared to generate multiple beams, the periodic on-off sequences controlling the static excitations are properly defined by means of an optimization strategy based on the Particle Swarm algorithm to afford desired multiple patterns at harmonic frequencies. The synthesis of simultaneous broadside sum and difference patterns, flat-top and narrow beam patterns, and steered multi-beams is investigated.
