I have been using the FEKO Student Edition 2018 with WinProp. I have made some preliminary power distribution analysis studies with different antenna patterns and I have seen that the software
automatically fills the low sidelobes and nulls in the imported antenna pattern while running the ray tracing solver. What I concluded is that everything that is 20 dB (or more) below the peak gain is set
to peak gain-20 dB by the solver in ProMan. I could not find any information on this (whether it is done intentionally, if it is possible to increase this dynamic range to more than just 20 dB etc.). Could
you please inform me about this issue? Thank you in advance.
