Beam steering in antenna

In this paper, we have presented the process of beam steering and its advantages. Nowadays compact sized low profile antennas with planer structures and low fabrication cost have become essential. Therefore the antennas need to have enhanced gain and steerable radiation patterns. Therefore, beam steerable antennas have become very popular in modern day antenna propagation. Beam steering technique reduces interference, saves power, increases gain and directivity of the micro-strip antenna. Beam steering antennas are defined so that the antennas can be able to form narrow directional beams with relatively low side lobes so that the beams can be electronically steered towards an intended target of transmission and reception. Beam steering antennas provide beam forming gain as opposed to diversity gain which is obtained from using MIMO type smart antennas.
