replace(plot,data)
removes all current data from a Smith chart, plot, and adds new
data to the Smith chart.
replace(plot,frequency,data)
removes all current data and adds new data to the Smith chart based on multiple data
sets containing frequencies corresponding to columns of the data matrix.
Plot the reflection coefficients of a dipole antenna.
Create a strip dipole antenna on the Y-Z plane. Calculate the complex S-parameters of the dipole antenna from 60 MHz to 90 MHz, with an interval of 150 kHz.
Plot S11 on a Smith chart for a reference impedance of 50 ohm.
d = dipole;
freq = linspace(60e6,90e6,200);
s_50 = sparameters(d,freq,50);
hg = smithplot(s_50,[1,1]);
hg.LegendLabels = 'S11 at 50#ohm';
Find S11 for a new impedance of 75 ohm. Replace the old S11 by the new S11 on the existing Smith chart.
