Resources
Material for this series
Notes, formula sheets and guides that stay useful after the episodes.
RF & Microwave Formula Sheet
One page: transmission-line equations, reflection coefficient, VSWR and return loss conversions, cascade noise figure, and the dB identities worth memorising.
Reading the Smith Chart
Where the chart comes from, how to move on it, and worked single-stub and L-network matches with the algebra shown alongside.
Antenna Parameters — Notes
Gain, directivity, efficiency, bandwidth, beamwidth and polarisation, each with the definition, the units and the measurement that would confirm it.
HFSS — Your First Correct Model
A step-by-step build of a microstrip patch, with the setup mistakes that silently produce plausible wrong answers called out at each step.
ADS — Matching Network Walkthrough
Build a matching network in ADS, verify it on the Smith chart, and check the result against the hand calculation.
Python for RF Engineers
scikit-rf, touchstone files, plotting S-parameters and automating a parameter sweep. Notebook included.
