yagiuda (Yagi-Uda Antenna Analysis Tool) yagiuda is a software tool designed to analyze the performance of Yagi-Uda antennas. By providing the dimensions and positions of each antenna element, the program calculates various important metrics including: - Gain - Input impedance - Front-to-back ratio - Beam patterns The package includes an optimization program that can help improve antenna designs and analyze their sensitivity to small mechanical errors.
