Hello,
I have one question, that I cannot find answer anywhere. I need to measure radiation pattern of the spiral antenna in a cavity. How this should be done?
If I understand correctly, the spiral antenna in a cavity should be a receiver antenna, which will rotate 360 degrees in theta. I need two perpendicular cuts in phi=0 and phi=90. The problem is, which antenna should I use for the transmitting antenna? I only have this one and few that are linearly polarized.. Can be a transmitter antenna linearly polarized antenna? Is it necessary to use both antennas with circular polarization? How the transmitting antenna should be turned?
Thank you very much for your answer.
