Phase-Only Planar Antenna Array Synthesis with Fuzzy Genetic Algorithms

This paper describes a new method for the synthesis of planar antenna arrays using fuzzy genetic algorithms (FGAs) by optimizing phase excitation coefficients to best meet a desired radiation pattern. We present the application of a rigorous optimization technique based on fuzzy genetic algorithms (FGAs), the optimizing algorithm is obtained by adjusting control parameters of a standard version...

Digitally 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...

Design of Reconfigurable Antenna Array using Improved Multiagent Genetic Algorithms

This paper presents a new method of optimizing a reconfigurable dual-beam antenna array using improved multiagent genetic algorithm(IMAGA). The reconfigurable design problem is to find element excitations that will result in a sector pattern main beam with low side lobes with additional requirement that the same excitation amplitudes applied to the array with zero-phase should result in a high ...
