Automated Robotic arms redefine the limits of antenna characterization. This paper
presents a method to estimate the far-field radiation pattern of antennas utilizing near-field
measurements through the use of a 6-axis robotic arm. The innovation of our project lies
in overcoming the current limitation of fixed scanning geometries, by extending them to any
possible spatial shape with the support of a 6-axis robotic arm.
The project is built and validated incrementally through a series of MATLAB functions,
utilizing the equivalence theorem as a NF to FF transformation method. Each stage builds
upon the previous ones and increases in complexity. Validation stages begin by simulating
infinitesimal dipoles and progress up to experimental validation of a tilted horn antenna. All
the validation steps are successfully met, except for an unexpected phase symmetry.
Our work sets a solid foundation for further development of this antenna measurement sys-
tem. The system will significantly improve antenna characterization by enabling more flexible
scanning grids.
