Hello
guys.
Recently, I am doing a project about direct antenna modulation. I have got questions about antenna.
1, the feed is the modulated signal, right?
2, if it is, why the radiation pattern keep constant since the frequecy and amplitude of input are changing.
( As my reference says, the pattern keep constant, in conventional modulation scheme, i.e the signal is modulated then up-converted to antenna.)
