Resumo(s)

Understanding antenna radiation patterns is crucial for optimizing wireless communication systems. Although simulation tools predict radiation patterns during development, environmental conditions in real-world settings substantially influence outcomes. Commercial measurement systems, though precise, are often prohibitively expensive for education. This work presents a low-cost, two-axis computerised system for measuring antenna radiation patterns at 868 MHz, integrating Arduino-based control, stepper motors, and power sensors. Tested with a Yagi-Uda antenna, it yields results consistent with simulations, serving as a practical tool for telecommunications classes. By enabling real-time visualization, this mechatronic platform enhances student understanding of antenna behaviour. Designs will be shared openly to support replication.
