Radome/LO problem

So how the US 5th generation figthers solve the problem of the radar/transparent radome?, most of the reflection should come from the radar antenna (AESA…which is pretty flat), some say the use of the inclined antenna could help (like in the f35 one), it seems their antennas does not use any kind of plasma screen like the IRBIS does, so the radome is done with RAM? is not that a counter productive solution?

I think the nose RAM does not affect the APG-77 frequencies..or at least most of them , but another radar using these frequencies could see clearly the radar antenna, so i dont think is a solution with out compromises
