Antenna Simulation Using Chebyshev Method

This article provides a comprehensive guide to simulating current distribution and radiation patterns using the Chebyshev method. The Chebyshev approach serves as an effective simulation tool that enables deeper understanding of antenna characteristics through polynomial approximation techniques. Prior to simulation implementation, fundamental concepts must be established, including current density definitions and radiation pattern calculation methodologies utilizing array factor formulations. Key implementation steps involve selecting appropriate antenna models and configuring parameters such as element spacing and excitation coefficients. During the simulation process, special attention should be given to computational aspects like error minimization through Chebyshev polynomial weighting and convergence verification via iterative algorithms. The core algorithm typically involves calculating Chebyshev polynomial coefficients to achieve desired side lobe levels, followed by current distribution synthesis using Fourier transform relationships. Final analysis of simulation results facilitates improved understanding of antenna performance characteristics and optimization of simulation methodologies through parameter tuning and pattern synthesis techniques.
