It can be so long that numetic error arizes and PC freezes for a few seconds when calculating this at user level.Ĥ)Antenna design software CAN NOT plot VSWR cycles.ĥ) direction arrows are missed on short plots. And you need to convert it to reflection coeff ? by the way. You have to build a crazy sandwitch of 2-screens long formulas for plotting input impedance of a multiport device. That is insane! And there is no option to change the input, or the X-axis to match it.Ģ)It plots STRAIGHT lines between points! Madness! You either linearly interpolate the impedance, or the S-parameters, and the lines should bend smoothly.ģ)There is no way to calculate and plot the input impedance. It plots normalized impedance and S parameters, but takes reflection coefficient as an input! Why HFSS keeps its awful Smith plot without improvement for years?ġ) It plots not what it takes as an input.
