I found a mistake, which causes Z=a+jb to be Z=a-jb, because the sign of a delay between CH1 and CH2 signals is defined in a reverse way.
Please see my new page Antenna for the detail. In my Gnuplot Script on line 13, “cursor1” should have a negative value when the delay of CH2 against CH1 is positive. Perhaps the line was correct originally, and I somehow changed the sign later.
