Smith chart
Interactive Smith chart impedance explorer
Plot impedance, SWR and reflection coefficients on a classic Smith chart. Drag the marker or enter values to explore matching behaviour.
Current SWR: 1.000
Smith chart workspace
Drag to move Γ
Normalised impedance z = 1.000 + j0.000
Drag the marker to adjust Γ. Constant resistance circles and reactance arcs highlight matching strategies.
Tip: trace proposed matching networks directly on the chart to see whether they follow constant-SWR circles.
