Abstract :
A suitable deterministic partitioning of large planar arrays in two kinds of properly shaped subarrays is shown to improve performances in terms of side-lobes peaks, directivity and aperture efficiency with respect to other existing solutions. The application of this simple idea to the case of large planar arrays with a reduced number of control points, useful in satellite applications, is demonstrated.
