Pattern Synthesis using Genetic Algorithm for Low Sidelobe Levels
For pattern synthesis of arrays, it is required to find out appropriate weighting vectors to yield a desired radiation pattern. It is well known that several methods for above purpose are available in literature. It is an established fact that when an attempt is made to reduce the first sidelobe level, the beamwidth increases. However, it is of interest in the present work to synthesize an arra...
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 کاملSynthesis 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 کاملA Pareto Elite Selection Genetic Algorithm for Random Antenna Array Beamforming with Low Sidelobe Level
Random antenna array (RAA) that uses the conventional beamforming method produces a poor beam pattern with high sidelobe level. This greatly reduces the performance and the efficiency of the antenna. The use of Genetic Algorithm (GA) to find the best positions for the antenna elements in RAA to lower the sidelobes has been widely researched. However, there has been no solution proposed for the ...
متن کاملWide Band Linear Printed Antenna Array with Low Sidelobe Cosecant Square-shaped Beam Pattern
A wide band, integrated linear printed antenna array with low sidelobe cosecant square-shaped beam pattern is presented. Array synthesis mainly about the wide shaped coverage, low ripple and sidelobe level (SLL) has been done using the modified least square method by matrix inversion. A printed dipole integrated with wideband balun has been chosen as the array element for wide bandwidth and goo...
