Antennas: The Physics Rabbit Hole Hidden Inside a Piece of Wire

The piece dives into RF fundamentals through SDR experiments and hands-on antenna building.

It connects charge, capacitance, inductance, and LC oscillation to show how resonance shapes antenna behavior.

Antennas are presented as devices that intentionally leak energy into space using electromagnetic fields.

The takeaway: antenna design depends on resonance and impedance matching, not just wire length.
