Smart Antenna Simulation Using MATLAB

Abstract

In the communication process, the signals are to be transmitted over a long distance to reach the distance then they may undergo through the obstacles, and signal scattering takes place. In our paper, we hired beam forming antennas that are controlled electronically so that the radiation pattern gets adjusted. The interfering signals are get suppressed and at the same time, the received signals are maximized. The smart antenna will decrease the noise by increasing the signal-to-noise ratio and have better system competence. In an adaptive beam, we can use a spacing of several antennas and the phase of the signal of each antenna array to control the shape as well as the direction of the signal beam. In this paper, we can observe the use of smart antennas using an adaptive beam method as a better system for signal transmission. Comparison for both omnidirectional antenna systems and smart antenna systems by simulating them. The advantages of a smart antenna system over an omnidirectional antenna are discussed in this paper. In this paper, it was seen that the higher the signal frequency (between 3 GHz, 4 GHz, and 5 GHz) had a more limited range of angles it could detect due to the beam width of the main lobe.
