Abstract-An innovative and general approach is proposed to the optimal, mask-constrained power synthesis of circular continuous aperture sources able to dynamically reconfigure their radiation behavior by just modifying their phase distribution. The design procedure relies on an effective a-priori exploration of the search space which guarantees the achievement of the globally-optimal solution. The synthesis is cast as a convex programming problem and can handle an arbitrary number of pencil and shaped beams. The achieved solutions are then exploited as reference and benchmark in order to design phase-only reconfigurable isophoric circular-ring sparse arrays. Numerical results concerning new-generation telecommunication systems are provided in support of the given theory.

“…There are a wide variety of techniques that have been developed for the synthesis of linear and planar arrays . To complete this kind of optimization, global optimization methods are usually used, such as genetic algorithms (GA) [3][4][5], particle swarm optimization (PSO) [6,7] and differential evolution (DE) algorithm. A hybrid genetic algorithm is used to synthesize desired far-field radiation patterns of conformal antenna array [3].…”

“…A hybrid genetic algorithm is used to synthesize desired far-field radiation patterns of conformal antenna array [3]. A comparison study between phase-only and amplitudephase synthesis of symmetric dual-pattern linear antenna arrays using floating-point or real-valued genetic algorithms is given in [4]. Unequally spaced linear array synthesis with side lobe suppression under constraints to beam width and null control using a design technique based on a comprehensive learning particle swarm optimizer (CLPSO) is presented in [6].…”

Abstract-An improved nonlinear least-square method is presented in this paper. This method changes the traditional least-square method's shortness of being sensitive to its initial conditions. Pattern synthesis for concentric circular arrays using nonlinear least-square method is introduced. The excitation amplitudes and phases of the array elements are optimized. This method can make the design of the feeding network much easier because the excitation amplitudes of the elements placed on the same ring are equal. The number of parameters to be optimized is reduced which leads to a faster simulation speed and makes the simulation results much more accurate. Also, the cost of designing the feeding network is reduced. The simulation results show the good agreement between the synthesized and desired radiation pattern. Also, the peak side lobe level (PSLL) of the synthesized radiation pattern is quite low.

Abstract-In this paper, the problem of designing linear antenna arrays for specific radiation properties is dealt with. The design problem is modeled as a single optimization problem. The objectives of this work are to minimize the maximum side lobe level (SLL) and perform null steering for isotropic linear antenna arrays by controlling different parameters of the array elements (position, amplitude, and phase). The optimization is performed using two techniques: Taguchi's optimization method and the self-adaptive differential evolution (SADE) technique. The advantage of Taguchi's optimization technique is the ability of solving problems with a high degree of complexity using a small number of experiments in the optimization process Taguchi's method is easy to implement and converges to the desired goal quickly in comparison with gradient-based methods and particle swarm optimization (PSO) Results obtained using Taguchi's method are in very good agreement with those obtained using the SADE technique.
