Also, the real part of the characteristic impedance is plotted with respect to frequency. Up to \(20\text{ GHz}\) a drop-off in \(Z_{0}\) is observed as frequency increases. This is due to both reduction of internal strip and ground ... WebA capacitor or inductor have imaginary impedance (no real part, just an imaginary part. The imaginary part is called "Reactance", and L and C are called "reactive elements". Reactance is the ratio of V/I, so it has the units of Ohms, just like resistance. The impedance of an inductor is Z = jwL.
