Guys, how do I make like a transceiver that follows a specific receiver. Like, my idea is basically putting sensors, for e.x. Ultrasonic Sensor or Infrared Sensor, to determine the distance, after that I use a bluetooth module or rf for the transceiver and receiver part then I add it to some servos to make it move because I want it so that when a moving object has the receiver, the transmitter/servo automatically follows that receiver/moving object.
Explain
without explanation we will not be able to help
Suitcases that follow people using Bluetooth radio have been around for years.

Look up "Fox Hunt" under armature radio, that may give you some ideas.
A fundamental question, if the receiver is moving, who will know? Does you design require the receiver to be powered on? Do you have a receiver in mind that will do what you plan?
Perhaps swap receiver and transmitter. Maybe human has a IR transmitter (i.e. beacon) and your fan has 3 IR receivers. Your code could try and orientate the fan to get the maximum signal on the middle IR receiver.
Maybe this is a variation of the old robot line following technique.
So, are you saying that the human has an IR receiver and the fan has 3 IR and when the human moves in the range of one of the IRs, then the servo moves at a specific position the same direction as the IR that's being activated
Also, how do I use an ir as a "beacon" that correlates with the 3 IRs connected with the servo
No, i'm suggesting the human has an IR (or other form of emitting device) transmitter. Your fan has 3 receivers - one points forward and the other 2 point 5 or 10 degrees off to the sides. The idea is that your receivers are moved to maximise the reception on the middle receiver - i.e. it's pointing at the human.
I've not explored further but maybe what this guy has done will be of use (ignore camera and insert fan):
