Synthesis of Flat Top Power Pattern in Linear Antenna Arrays using Differential Evolution Algorithm
This work describes about the synthesis of the flat top power pattern of linear antenna array using differential evolution (DE) algorithm as an optimizing algorithm. In this work a flat top beam pattern of sharp transition (T), low Side Lobe Level (SLL) and very little ripple (R) has been achieved. To reduce the design cost of the feed network of the synthesized pattern, only the complex excita...
متن کاملModified Differential Evolution Algorithm for Pattern Synthesis of Antenna Arrays
A modified differential evolution algorithm (MDE) for pattern synthesis of antenna arrays is proposed in this paper. By employing the novel strategies of best of random mutation and randomized local search, the convergence of standard differential evolution algorithm (SDE) is significantly accelerated. Five standard benchmark functions are optimized to testify the proposed algorithm by comparis...
متن کاملDynamic Thinning of Antenna Array Using Differential Evolution Algorithm
Dynamic thinning is a process by which the total number of active elements in an antenna array is reduced under real time conditions without causing major degradation in system’s performances. This paper suggests a technique by which a thinned antenna array is designed by simple differential evolution(DE) algorithm overcoming the difficulties of large and rugged solution space and slow rate of ...
متن کاملSynthesis of Linear Antenna Array Using Firefly Algorithm
Antenna array is the most important aspect to improve the communication process. The objective of this paper are to minimize the maximum side lobe level (SLL) and perform null steering for linear antenna arrays by controlling different parameters of the array elements (phase, position and amplitude). The Nature inspired optimization methods like Taguchi’s Optimization Method (TM), Self-Adaptive...
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...
