To respond to your other comments, s11 is a polar plot of complex reflection overlaid on top of the smith chart, where the origin (0,0) is at the center of the smith chart (50 ohm location) so you can plot both s11 and z on the same graph.
Half is “capacitive” = negative imaginary part. It also allows the calculation of the admittance y = 1/z of an impedance. Preview image of smith chart graph paper: The impedance is represented by a normalized impedance z.
Note for the normalized impedance plane, a vertical line rc= r and a horizontal line xc= iĪd shop devices, apparel, books, music & more.Īll the engineering complications that were raised were resolved by this.
