Abstract

Single element antennas have very little capability of variation of antenna gain pattern. For a desired directivity, shape of beam and steer able beam, array antenna is widely used in wireless network. Relative magnitude of feed currents, relative phases or separation between antenna elements, geometrical configuration of array are responsible for the overall radiation pattern. The weighting factor of each antenna element is governed by an adaptive algorithm based on input signal and desired signal to achieve dynamic shaping of antenna beam. In this paper, both single and multiple elements adaptive array antenna system is used to tune the gain in such a way that the gain is enhanced in the direction of desired signal and reduced in the direction of interference or jamming signals.
