Design and optimization of Slotted Arrays by Power Synthesis Approach

In this paper, we present a method for the design and optimization of slotted arrays capable of radiating a maximally focused beam in a given direction by controlling sidelobe level. The pattern synthesis problem is reduced to a convex optimization problem by using the optimal power pattern synthesis approach. The optimization algorithm is implemented by interfacing an in-house developed code with an electromagnetic CAD. Two design examples are provided to show effectiveness of the proposed method, namely a linear polarized (LP) and a circular polarized (CP) linear slotted arrays etched on standard rectangular waveguides.
