“…4,5 In recent years, many authors have proposed various synthesis methods for optimizing elliptical antennas. [6][7][8][9][10][11][12][13][14][15][16][17][18] In paper, 6 authors have designed steerable concentric ring arrays and the amplitude and phase of excitation current of the array elements are optimized using Genetic Algorithm (GA) to get a low value of SLL in the radiation pattern. In paper, 7 a non-dominated GA is used to enumerate the trade-off graph of a circular phased array antenna having nonuniform element spacing to minimize the SLL and width of the main beam.…”

This study, describes the design problem of a thinned multiple concentric elliptical arrays of uniformly excited isotropic antennas using meta-heuristic optimization algorithms; Teaching Learning Based Optimization (TLBO), Crow Search Algorithm (CSA) and Moth Flame Optimization (MFO) algorithm. Two simulations are performed here. In simulation 1, the synthesis of the thinned array structure is presented in the vertical plane at a scanning angle 30 and in simulation 2, the synthesis is performed in the horizontal plane. In

“…A Concentric ring array of 61 number of patch antennas are designed in paper. 11 The aim is to find out the excitation levels using harmony search algorithm and PSO at a frequency of 2.8 GHz. In this design the mutual coupling effect is also considered to obtain a reconfigurable isoflux pattern.…”

“…For example, in [2], the CRA is designed for the application of geostationary earth orbit satellites with isoflux radiation. For a reconfigurable isoflux pattern, design of concentric ring antenna arrays with 61 elements of disk-patch antennas is proposed in [3] which is significant in reducing the antenna hardware complexity with heat dissipation system and volume occupied in a satellite. In [4], synthesis of patch CRAs to be used in satellites with terrestrial global coverage patterns at the L band is explained.…”

This paper proposes the novel application of three meta-heuristic optimization algorithms namely crow search algorithm, moth flame optimization, and symbiotic organism search algorithm for the synthesis of uniformly excited multiple concentric ring array antennas. The objective of this work is to minimize the sidelobe level (SLL) and maximize the peak directivity simultaneously. Three different cases are demonstrated separately with various constraints such as optimal inter-element spacing and/or optimal ring radii. Comparative study of the algorithms using common parameters such as SLL, directivity, first null beam width, best cost, and run time has been reported. Investigation results prove the superiority of case 3 over other cases in terms of directivity and SLL. This work demonstrates the potential of these algorithms.

“…Antenna array plays an important role in technology, including mobile communication, radar system, satellite, and medical treatment. For example, in [1], a concentric ring array antenna is designed for reconfigurable isoflux pattern, which uses 61 elements, and the frequency is 2.8 GHz. The antenna arrays can reduce the volume occupation and complex feeding and heat dissipation systems in a satellite antenna system.…”

To lower the peak sidelobe level (PSLL) of sparse concentric ring arrays, a method with multiple design constraints that embed a function model into modified real genetic algorithm (MGA) and select the grid ring radii as optimization individual to synthesize sparse concentric ring arrays is proposed. The multiple constraints include the array aperture, the minimum element spacing, and the number of elements. The proposed method dynamically calculates the ratio of element on each ring, and it has a faster convergence rate than other algorithms. The MGA uses real number to code the optimization variable, and it reduces the complexity of coding and improves the search efficiency. Finally, the results demonstrate the accuracy and effectiveness of the algorithm.
