“…However, generation of cosec 2 beam and pencil beam using a common set of discrete elements amplitudes often faces high side lobe with large ripple problem. Several approaches reported in the literature for generating beam patterns are as follows [1][2][3][4][5][6][7][8][9][10].…”

“…Durr et al generates shaped beams (flattop and cosecant) from linear antenna array where both uniform and Gaussian distributions of common amplitudes are used for the generation of patterns, and different sets of phases for both beams are computed using WoodwardLawson technique [4]. Azaro et al find the desired values of VSWR by minimizing the linear dimension of a monopole antenna using PSO, and the simulated results are also compared with experimental values [5].…”

Abstract-In this paper a pattern synthesis method based on Differential Evolution Algorithm (DE) is presented to generate dual beam patterns from a planar array of isotropic antennas. These are cosec 2 pattern and pencil beam pattern. These patterns are obtained by finding out an optimum set of common elements amplitude (for cosec 2 pattern as well as a pencil beam pattern), and a set of phases, for cosec 2 pattern only. 4-bit discrete amplitudes and 5-bit discrete phases are used to reduce the design complexity of feed network. The beam patterns have been generated in two different azimuth planes instead of one particular plane. The evaluated excitations are also verified by considering a range of arbitrarily chosen azimuth planes, where the patterns are generated with some minor variations of the desired parameters. Obtained results clearly established the effectiveness of the proposed method.

“…Generally multiple radiation patterns are obtained by switching between the excitation phases distributions of the elements while sharing common amplitude distributions. Several methods of generating multiple patterns from a single antenna arrays appeared in the literature [1][2][3][4][5][6][7][8][9][10][11].…”

“…Design of phase-differentiated multiple pattern antenna arrays based on simulated annealing algorithm have been described by Diaz et al [2]. Durr et al proposed a phase only pattern synthesis method to generate multiple radiations of pre-fixed amplitude distribution with modified Woodward-Lawson technique [3]. The design of a phase-differentiated reconfigurable array [4] using particle swarm optimization in angle domain has been described by Gies and Rahmat-Samii.…”

Abstract-Reconfigurable antenna arrays are often capable of radiating multiple patterns by modifying the excitation phases of the elements. In this paper a method based on Firefly Algorithm (FA) has been proposed to obtain dual radiation pattern from a concentric ring array of isotropic elements, by finding out two different combinations of states for the switches, which are assumed to be connected with the rings of the array, along with optimum set of 4-bit radial amplitude and 5-bit radial phase distributions of the array elements for the specific switch combinations. The optimum excitations of the array elements in terms of discrete amplitudes and discrete phase, and the different switch combinations for the specific excitations are computed using Firefly Algorithm. To illustrate the effectiveness of Firefly Algorithm, the two beam pairs have been computed by the same procedure from the same array, using Particle Swarm Optimization (PSO) algorithm, without changing their design criteria. Results clearly show the superiority of the Firefly Algorithm over Particle Swarm Optimization to handle the proposed problem.

“…In the past decades, this problem has been one of the most active and prolific research areas since the pioneering work of Bucci et al [1,2]. Moreover, this problem has also been a central and well studied problem with a strong engineering background in the field of manufacturing and telecommunications science [3,4]. In order to solve this problem, many methods have been proposed to obtain the multi-pattern arrays in previous literatures [4][5][6][7][8].…”

Abstract-Multi-beam antenna arrays have important applications in the field of communications and radar. The reconfigurable design problem is to find the element in a sector pattern main beam with side lobes. The same excitation amplitudes applied to the array with zero-phase should be in a high directivity, low side lobe pencil shaped main beam. This paper presents a new method of designing a reconfigurable antenna with quantized phase excitations using an improved artificial bee colony, called IABC. Compared with subsequent quantization, experimental results indicate that the performance of the discrete realization of the phase-excitation value can be improved.
