Reduction of Side Lobe Level of Thinned Phased Array Antenna using Genetic Algorithm
Thinned phased array antenna is useful for Radar and satellite communications. Main drawback of phased array antenna is generation of side lobes and grating lobes when the beam is titled from broadside direction toward the end-fire direction. This paper reports the optimization of thinned phased array antenna using genetic algorithm (GA). By varying the tilt angle form broadside direction main ...
متن کاملSynthesis of Linear Antenna Array using Genetic Algorithm with Cost Based Roulette to Maximize Side lobe Level Reduction
-This paper discusses the deployment of Genetic algorithm optimization method for synthesis of antenna array radiation pattern in adaptive beam forming. The synthesis problem discussed is to find the weights of the antenna array elements that are optimum to provide the radiation pattern with maximum reduction in the side lobe level. This technique proved its effectiveness in improving the perfo...
متن کاملPhase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods
In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...
متن کاملReduction of Side lobe level in linear antenna array using PSOGSA algorithm
In the antenna arrays the side lobe level is main problem which causes wastage of energy. This paper describes the application of a recently developed metaheuristic algorithm, known as the Particle Swarm Optimization Gravitational Search Algorithm(PSOGSA) to optimize the spacing between the elements of the linear antenna array to produce a radiation pattern with minimum side lobe level. Numeric...
متن کاملSide Lobe Reduction of a Concentric Circular Antenna Array using Genetic Algorithm
A concentric circular antenna array (CCAA) consists of elements positioned on the periphery of imaginary circles on a plane having a common centre and different radii. The simplest way to feed the elements of such an array is to use uniform excitation. However, with a non-uniform excitation profile, considerable reduction of the side lobe level (SLL) may be achieved at the cost of the added com...
