Multibeam Antennas Array Pattern Synthesis using Hybrid Particle Swarm Optimizer with Breeding and Subpopulations Algorithm
In this paper a new effective optimization algorithm called hybrid particle swarm optimizer with breeding and subpopulation is presented. This algorithm is essentially, as PSO and GA, a population-based heuristic search technique, now in use for the optimization of electromagnetic structures, modeled on the concepts of natural selection and evolution (GA) but also based on cultural and social r...
متن کاملSoftware for Synthesis of Radiation Patterns by Linear Antenna Arrays
This paper presents the characteristics of a software developed on MatLab Scripts to obtain the synthesis of radiation patterns, using linear antenna arrays. Several classical techniques have been considered such as Schelkunoff method, Fourier series and transform methods, Woodward-Lawson method, Taylor line-source methods. In all those cases, algorithms were developed and the results agree wit...
متن کاملSynthesis of Multibeam Antennas Arrays with a Modified Particle Swarm Optimization Algorithm
In this paper, we intend to study the synthesis of the multibeam arrays. The synthesis implementation’s method for this type of arrays permits to approach the appropriated radiance’s diagram. An adaptive particle swarm optimization algorithm (APSO) is proposed to synthesis multibeam antenna arrays. The problem is formulated and solved by means of the proposed algorithm. The examples are simulat...
متن کاملSynthesis of Antenna Arrays of Maximum Directivity for a Specified Sidelobe Level
Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...
متن کاملMAC Layer Performance with S teerable Multibeam Antenna Arrays
In this paper, we are concerned with the performance at the media access control (MAC) layer of the protocol stack when multibeam adaptive antenna arrays are employed at the base station site. Specifically, we analyze the performance of slotted ALOHA when the base station receiver uses multibeam antenna arrays capable of steering the beams selectively on smaller sectors. The effect of different...
