Jurnal : Antenna Array Side Lobe Reduction by ImplementingNon – Uniform Amplitude Using Tsukamoto FuzzyLogic Controller(Jurnal Teknik Informatika)
Abstract
This paper deals with a scheme of Antenna array side lobe reduction by varying amplitude of each element of the antenna array using the Tsukamoto fuzzy logic controller. Here it has been tried to reduce the Side Lobe Level of the antenna array radiation pattern by changing the amplitude of the antenna array elements. Spacing between the antenna array elements and the corresponding phase - shift is given in the input of the Tsukamoto fuzzy logic controller and corresponding values of amplitude is obtained at the output of the controller. Implementing the newlyobtained values of amplitude to the each element of the antenna array, the new radiation pattern with reduced side lobe level will be obtained.

I.IntroductionAntenna array is a set of several antenna elements. It is mainly used to generate radiation pattern with a high directivity. In case of practical use, it is desirable to have the radiation in a certain direction. The task, in general, is to find out the antenna configuration as well as geometrical dimension and excitation distribution [1]. Any practical use of an antenna array, it should ensure the minimum acceptable radiation pattern under certain constraints. The aim is to determine the physical layout of the antenna array that produces a radiation pattern which is nearest to the desired pattern [2]. This process is, in general, called synthesis. We can synthesize the antenna array by reducing its side lobe level or by decreasing its null point etc. There are various methods that can be used for the antenna array side lobe reduction, namely GAs [3-5], Simulated Annealing (SA) [6], Tabu Search [7], Taguchi’s method [8], Memetic Algorithm (MAs) [9], PSO [10], Fuzzy Genetic Algorithm [11], Fitness-Adaptive Differential Algorithm[12], Fuzzy PSO Algorithm [13], Bacteria Foraging Optimization Technique [14] etc. In this work we have tried to synthesize the antenna array radiation pattern by implementing non – uniform amplitude using fuzzy logic [15]. For this work we have used the Tsukamoto fuzzy logic controller.
