The video walks through practical antenna design from theory to measurement, presented by Quarterwave co-founder Nicola. It explains key RF concepts—S11 reflection coefficient, 50-ohm matching, Smith chart matching techniques, radiation efficiency and directivity—and demonstrates rapid prototyping, simulation, and real-world integration tests. Nicola emphasizes the importance of matching and efficiency for power delivery, range, and battery life, and shows how enclosure and environment affect antenna performance. The session also compares measurement tools from inexpensive DIY methods to professional equipment and highlights iterative tuning in the product’s intended environment.

The video examines how broken or split reference planes in a PCB stack‑up affect electromagnetic fields around high‑speed signal traces. Using Symbur simulations, the presenter compares a symmetric strip‑line with solid ground planes to configurations where one plane contains a...
