Synthesis of Wideband Rotationally Symmetric Sparse Circular Arrays With Multiple Constraints

Wideband rotationally symmetric sparse circular arrays (RSSCAs) with multiple constraints are synthesized in this letter. First, the circular aperture is partitioned into several rotationally symmetric sections, and each section consists of some annular sectors (ASs). The element positions and eleme...
