The main aim of this paper is to reduce the first four Side Lobe Levels (SLLs) of the linear and circular array antennas using gatool, which is the one of the simplest and efficient tool in MATLAB. This is employed in Radars and communications in order to reduce jamming effects, EMI and heavy clustering effects. Here amplitude of the elements of the antennas is taken as variables to control. And finally the design currents are given and sum and difference pattern plots for different number of elements for linear and circular array antennas. Simulation results are presented for above with rectangular plots. Successful applications show that gatool can be used as a general tool for pattern synthesis of arbitrary arrays.
