Development a New Technique Based on Least Square Method to Synthesize the Pattern of Equally Space Linear Arrays
Using the sampled data of a desired pattern is a common technique in pattern synthesizing of array factor (AF) of antenna arrays. Based on the obtained data matrix, Least Square Method (LSM) is used to calculate the exciting coefficient of array elements. The most important parameter, which involves the accuracy and complexity of calculation, is the sampling rate of the desired pattern. Classic...
متن کاملSynthesis of Non-Uniform Amplitude equally Spaced Antenna Arrays Using PSO and DE Algorithms
In recent years Evolutionary computation has its growth to extent. Synthesis of non-uniform linear antenna arrays is one of the most important electromagnetic optimization problems of the current interest. In this paper, the design of non-uniform linear antenna arrays with optimum side lobe level reduction is investigated. Two global evolutionary optimization methods are Particle Swarm Optimiza...
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 کاملTemplate Synthesis of Carbon Nanofibers Containing Linear Mesocage Arrays
Carbon nanofibers containing linear mesocage arrays were prepared via evaporation induced self-assembly method within AAO template with an average channel diameter of about 25 nm. The TEM results show that the mesocages have an elongated shape in the transversal direction. The results of N2 adsorption-desorption analysis indicate that the sample possesses a cage-like mesoporous structure and th...
متن کاملDigitally Excited Reconfigurable Linear Antenna Array Using Swarm Optimization Algorithms
This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...
