I'm just measured my antenna with spectrum & vector network analyzer and used smith chart to see if my antenna is in 50 ohm range, i get these rezults:
Now I want to match my antenna, but the thing is that I don't understand how I have to write Im number in Smith V4.1, I mean I have to put - in front of 12.02 or no? Because I'm seeing different aswers.

Why i'm asking, and not changing r+jx to real/imag function, because i did this measurements in school, and now i can't go there and do it again.
