Abstract
In this letter, we explore the potential for the application of fractal subarrays to the generation of sum and difference patterns. For the purposes of this investigation, a standard planar array is decomposed into two subarrays: one in the form of a Sierpinski carpet, and the other consisting of its complement. A methodology is then introduced for feeding the two subarrays in order to produce either a sum or a difference pattern. A particular example is considered in which directive gain plots are obtained for both the sum and difference modes of a 27×27 planar array.
