My end project for my Bachelor of Science in Electrical Engineering was about the development of a ’Reflection Coefficient Measurement System for an In‑Flight Antenna Validation Experiment’. The aim was to test an inflatable antenna design in harsh conditions similar to those found in space. The development system was first designed and calculated on paper, and subsequently modeled for 3D EM simulation. Next, I created the design in the PCB design software and send it off for manufacturing. Finally, the system was tested using a Vector Network Analyzer (VNA).
