Abstract :
There are instances in phased array antenna design in which, for structural reasons, it becomes necessary to introduce an "interruption" in the regular lattice spacing of the antenna elements. This work shows that the application of a GA to an interrupted phased array results in a design that minimizes the relative sidelobe level of the resulting pattern. This design relies not only on the introduction of a non-uniform aperture distribution, but also on the placement and width of the interruption.
