Hello everyone.
I need you to help me about determination of antenna gain. I had a radiation pattern test nowadays and need to find out which way is the correct way to determine antenna gain. I will use substitution method for gain comparison. I am going to use a reference gain known antenna with my AUT. My set-up includes a test software and a turn table with network analyzer. I rotated the turn table in 360 degress with 5 degrees step and record s21 in a frequency sapn between 380-400 mHz with 0.25 KHz step widths. What i need to now, i need to calculate the gain in frequency. Should i need to use every peak transmission in any degrees or should i use direct s21 in certain degree?
Thank you for your help.
