Antenna array synthesis by implementing non-uniform amplitude using Fuzzy logic

This paper deals with a scheme of Antenna array synthesis by varying amplitude using Fuzzy logic. Here it has been tried to get new radiation pattern of the antenna array by changing the amplitude of the antenna array elements. Spacing between the elements of the antenna array and the corresponding phase - shift is given to the input of the Fuzzy logic controller and corresponding defuzzified values of amplitude is obtained at the output of the controller. Putting the new values of amplitude to the each and every element, the new radiation pattern will be obtained. This method can be used for the reduction of the Side Lobe Level (SLL) of the antenna radiation pattern to a certain extent where the exact values of the spacing and phase - shift is not known.
