Analytical synthesis technique for uniform-amplitude linear sparse arrays

In this work, a novel synthesis technique for the design of linear uniformly fed sparse arrays has been presented. Such method, based on a fully analytical procedure, is able to mimic a given array factor mask without using computationally demanding optimization algorithms. As an example, an array of 51 antennas having aperture L*max = 24.5 λo has been designed in order to synthesize a very complex radiation mask useful in a large variety of applications.
