Design of beam steered weighted array with sidelobe cancellation

Smart antenna is one of the fastest emerging technologies. An antenna array is a set of individual antennas that are used for transreceiving the electromagnetic signals. In this paper weighting method is used to control the behaviour of the array along with sidelobe cancellation techniques. Three basic algorithms that are Kaiser-Bessel, Blackman and Gaussian are used to find the array weights. As a result an array factor of amplitudes 1, 0.6561, 0.2521 with side lobes which are being cancelled to yield maximum directional beam.
