Impedance Matching of Antenna and Amplifier
This is where Smith Charts are used: impedance matching. There are some versions that can be downloaded, but Is used the online tools here and here.
Your table of S11 parameters got me a "calibrated guess" of 0.186, angle -86.191 for the parameters at 150MHz. The first link helped me convert that to an actual impedance of: 47.7977 -j8.3772 Ohms.
I used that as a "source impedance" for the chart at the second link. Adding a parallel capacitor of 4.94pF, and a series inductor of 21.88nH, tuned the impedance back to 50 Ohms. In practice, you'd probably use a 22nH inductor and a tuning cap around 5pF.
