So I modify may question: "Are in today transmitters the "variations of
Tesla
coils" or the "variations of Marx generators".
Or "is possible to do the transmitter without coils"?
If Yes, when was the first?

I have never seen a transmitter (even that in a mobile phone).

Neither, some of Tesla's equipment may have made use resonance, but they
are not the root of resonant circuits used in modern equipment.
ie Tesla coils did not turn into the circuits used today.

"is possible to do the transmitter without any coils"?
