A Toolbox of Subarrays for Optimizing Wide-Angular Scanning Arrays Using Trade-Offs between Scan Loss and Side Lobe Level

A novel approach is proposed for building a planar array derived from linear arrays using a toolbox of different types of subarrays located parallel and perpendicular to the linear array axes. The array design assumes constant element patterns and focuses on rectangular array applications with one dimensional, wide-angular beam scanning....

Use of subarrays in linear array for improving wide angular scanning performance

The scanning performance of wide-angular scanning linear arrays is primarily degraded by the limited angular profile of the employed elements' patterns. This paper introduces an innovative strategy for compensating this degradation by using subarrays. Our design uses a uniform linear array with half-wavelength spaced elements, supplemented by...
