“…Two main factors, which determine the sidelobe levels (SLLs), are the power distribution between the elements and the distance between them. Typical demands are SLLs -20 dB [1], relative to the main lobe. SLLs from -30 to -20 dB can be typically achieved solely by the power distribution, but for higher lobes suppression, the distance between the elements must be considered as well.…”
