Accurately characterizing antenna radiation patterns in the millimetre-wave (mmW) frequency range presents significant challenges due to the short wavelengths involved. A measurement system that incorporates a 6-axis robotic arm is implemented to gain more positional control over the antenna measurement. This thesis presents the software to control the system, including the robotic arm and a Vector Network Analyser, in a user-friendly manner. Additionally, it dives into the influence of the characteristics and movement of the robotic arm on the setup. To ensure reliability and maintainability of the codebase, the software was structured using several objects and data classes, each responsible for a specific part of the system. Tests of the system showed a solid foundation of the graphical user interface and the back-end software architecture. Analysis of the repeatability of the system revealed that results may deviate by magnitude differences of 0.8 dB and phase differences up to 30°. Compared to a calibrated position of the system, displacements in individual joints led to significant phase difference of up to 20°. There was no correlation found in deviations of magnitude or phase response and the settle time between the movements of the robot and the measuring of the VNA.
