IMPROVEMENT OF FAR FIELD RADIATION PATTERN OF LINEAR ARRAY ANTENNA USING GENETIC ALGORITHM
Journal Title: ICTACT Journal on Communication Technology - Year 2010, Vol 1, Issue 1
Abstract
In this paper, the beam pattern of Linear Array Antennas with isotropic elements is examined. The design goal is to reduce the sidelobe level with a minimum beamwidth increase for the far field radiation pattern of the array by varying its electrical as well as its physical configuration. In this paper the cases of a uniformly excited and uniformly spaced array, uniformly excited and non-uniformly spaced array, and a non-uniformly excited and uniformly spaced array are examined for both symmetric as well as asymmetric array, and a comparison is done between them. Real Coded Genetic Algorithm (RGA) is used to find the optimal locations as well as the optimal excitations for the problem as per the cases considered.
