Does this feature depends on changing the phase of the transmitted signal ?
 

Are you referring to an antenna with a fixed electrical downtilt?

If so, that antenna will have multiple internal elements with a phase difference between them. To the user though, there is still just one RF connection and the user does not change the phase, the phase offset between elements is done inside the antenna.
 
Your antenna must be an array of elements (at least two). Most commonly you have some kind of phase control for each element for beam steering.
 
electrical tilt is basically applied on an antenna when the changes to feed signal is done!
 

Hi,

could you please explain more ?

Best regards
