Optimum Synthesis of Pencil Beams with Constrained Dynamic Range Ratio

Figure 5

Distribution of all-positive (blue) as well as positive-and-negative (red) coefficients in pencil beam arrays with various numbers of elements and beamwidth of 12°, obtained by minimization of SLL and constrained DRR. Black curve indicates maximum DRR, which is achieved in DRR-unconstrained design.
