Which component generates and amplifies the EMF signal?

Explanation:
Generating and amplifying the EMF signal is handled by the transmitter. It contains the oscillator that creates the carrier frequency and RF power amplifiers that boost the signal to the power level needed to drive the antenna. The transmission line merely carries this energy to the antenna and can add losses or impedance changes but does not increase power. The antenna radiates the energy as EM waves, not by amplifying it. The ground provides a reference and return path for currents but doesn’t generate energy.
