Antenna Radiation Pattern with MATLAB Implementation

I have developed an antenna radiation pattern program using MATLAB. This program implements radiation patterns for uniform linear arrays and includes a complete implementation of the MUSIC (Multiple Signal Classification) algorithm. The antenna radiation pattern graphically represents an antenna's radiation characteristics across different directions. In uniform linear arrays, antenna elements are equally spaced, which provides enhanced pattern resolution and directional control. The MUSIC algorithm is a high-resolution direction of arrival estimation technique that leverages the signal subspace characteristics of antenna arrays to precisely determine signal arrival angles. The implementation includes key functions such as array manifold calculation, covariance matrix computation, and eigenvalue decomposition for signal subspace separation. Through these programs, users can effectively analyze and understand antenna directional performance, with capabilities for pattern visualization, beamforming analysis, and spatial spectrum estimation.
