Abstract: In this paper the radiation pattern of Uniform linear arrays like Broad Side Array and End Fire Array with reduced side lobes is generated. For some applications, single element antennas are unable to meet the gain or radiation pattern requirements. So combining several single antenna elements in an array can be a possible solution. Array is a system of similar antennas oriented similarly to get greater directivity in a desired direction. Various techniques can be used to reduce the side lobes in the radiation pattern. Here, we employ windowing techniques for the reduction of side lobes. MATLAB (7.12) is the Simulation Platform. Various Windows used are Rectangular, Hamming, Hanning, Gaussian, Blackmann, Bartlett, Tukey, Parzen, Kaiser Windows

Keywords: radiation pattern, Directivity, Hamming, Hanning, Gaussian Bartlett
