Sažetak
The synthesis of array patterns with reduced dynamic range ratio (DRR) of excitation coefficients is important because it enables better control of mutual coupling between antennas and simplifies the design of the feeding networks. In this paper, a method for global optimization of linear pencil beams with constrained DRR is presented. The optimization problem is formed which minimizes the sidelobe level for a given beamwidth and DRR. This problem is solved by using branch and bound algorithm. The proposed method supports positive and negative coefficients including the values of 1 and 1. The design is fast, enabling interactive experimenting with various numbers of antenna elements and DRRs.
