skrf.tlineFunctions.input_impedance_at_theta(z0, zl, theta)[source]

Input impedance from load impedance at a given electrical length.

Input impedance of load impedance zl at a given electrical length, given characteristic impedance z0.

  • z0 (number or array-like) – characteristic impedance

  • zl (number or array-like) – load impedance

  • theta (number or array-like) – electrical length of the line (may be complex)


zin – input impedance at theta

Return type:

number or array-like
