Thanks for the input. I am trying to design a wideband (1-2 octaves) conformal spiral array for a project. The axial ratio so far was less than ideal (avg. about 4 dB with some lossy backing and 6-7dB just over a ground plane).
I always see a 3dB axial ratio cited as metric for CP antenna performance. What negative effects will I see receiving with an ideal RHCP antenna a RHCP signal, say 6dB axial ratio, beyond a slight loss (1 or 2dB) in receive power do to the mismatch? Thanks!
