MATLAB Simulation of 1D Linear and 2D Planar Phased Array Antennas

We conduct MATLAB simulations for both 1D linear and 2D planar phased array antennas to demonstrate their beam steering and multi-beam formation capabilities. The simulation includes implementation of phase calculation algorithms using element spacing and steering angles, with code examples showing how to manipulate complex weights for each antenna element. Through these simulations, we observe the working principles and performance characteristics of phased arrays, including signal radiation/reception patterns, beamforming techniques, and dynamic directional control. The MATLAB code allows parameter modification to explore different operational modes and performance features, such as varying frequencies, different numbers of antenna elements, and alternative beamforming algorithms like DFT-based or MVDR methods. These investigations help deepen understanding of phased array fundamentals and applications, providing support and guidance for their implementation in communications, radar systems, medical imaging, and other fields. The simulation includes visualization functions to plot radiation patterns and beam direction changes in real-time.
