Design and simulation of an adaptive beam smart antenna using MATLAB

Abstract

<span id="docs-internal-guid-ad3b6b0d-7fff-2d92-685e-3d423ac2713f"><span>Signals transmitted over a long range of distance may pass through several obstacles and scatter, taking multiple paths to reach the receiver. Beamforming antennas are controlled electronically to adjust the radiation pattern following the first received signal. This allows the antenna to maximize the received signal and consequently, suppress the interfering signals received. A smart antenna should be able to diminish noise, increase the signal to noise ratio, and have better system competence. The adaptive beam makes use of the spacing of the several antennas and the phase of the signal of each antenna array to control the shape and direction of the signal beam. This paper focuses on the use of smart antennas using an adaptive beam method as a better system for the transmission of signals. A simulation between the existing Omnidirectional antenna system and the smart antenna system will be made and compared. The paper will discuss the corresponding advantages that a smart antenna system has compared to the Omnidirectional antenna system.</span></span>

Implementation method of MATLAB data processing in radar antenna pattern testing

“…In the current research on directional patterns, there are two types of differentiation phenomena: the first is that MATLAB mathematical tools are only used for antenna performance simulation. For example, reference [3] proposes a MATLAB design and simulation method for adaptive beam smart antennas, and reference [4] carried out the design and research of array antenna directional pattern simulation system. The two literature mainly used MATLAB to simulate directional patterns, but did not apply MATLAB tools in directional pattern measurement work; The second scenario is the construction of an antenna measurement system that achieves the drawing of directional patterns without utilizing MATLAB tools.…”
