Optimum Synthesis of Pencil Beams with Constrained Dynamic Range Ratio

Table 11

Beam efficiency and dynamic range ratio of DPSS pencil beam arrays [16] and proposed arrays with minimum DRR and BE_des of 99.9%, 99.5%, and 99.0%, together with design time of proposed arrays, t_design. Improvements are highlighted in bold.
